Mathematics in Finance: Systemic Risk

At the SIAM Annual Meeting held in Minneapolis in July, Dr. George Papanicolaou of Stanford University surveyed a topic of great relevance today—models for systemic risk and the implications that can be drawn from them. Laying out the picture of an evolving system with a large number of interconnected components, he described Systemic Risk as the probability of overall failure of the system. Papanicolaou spoke about the effect of electronic trading and automated exchanges increase in increased liquidity and risk, illustrating the significance of systemic risk in current mathematical finance research.

New York Times reports on SIAM and scientific community concerns over GSA Act

Earlier this summer, when it was revealed that officials from the General Services Administration, the agency that oversees the business of the federal government with a $26.3 billion annual budget, spent more than a quarter-million on a lavish, one-day awards ceremony, the Obama administration tightened budgets and placed restrictions on the amount of money that can be spent on similar events.

This, however, has caused constraints in the science and technology community, as restrictions were also imposed on conference and travel expenses for representatives from government agencies such as the National Science Foundation (NSF), the Department of Energy, NASA,  and the Defense Department, including government labs. This impedes scientific discussion and collaboration that routinely occurs at scientific and technical meetings between government agencies and researchers from private organizations and institutes.

On September 10, SIAM along with the Association for Computing Machinery (ACM), the Computing Research Association (CRA), and the Institute of Electrical and Electronic Engineers, Inc. – USA (IEEE-USA) sent a joint letter expressing concern over new restrictions on conferences and travel expenses in three pieces of legislation that are currently under consideration by Congress (GSA Act, DATA Act, and the 21st Century Postal Reform Act).  The letter was sent to House and Senate leadership, Sponsors of the bills (Reps. Joe Walsh and Darrell Issa, Senator Lieberman), Chair and Ranking Member of the committees of jurisdiction (House Oversight Committee, Reps. Issa and Cummings; Senate Homeland Security and Governmental Affairs Committee, Senators Lieberman and Collins), White House Office of Science and Technology Policy Director John Holdren, and White House Office of Management and Budget Director Jeffrey Zients. The letter requests exemptions for any new restrictions for recognized scientific, technical, and educational meetings from the proposed limits.

The New York Times reported on the joint letter and the concerns expressed by the scientific community this week.

Three SIAM Journals get new Editors-in-Chief

SIAM is happy to welcome Arnd Scheel, Jean-Michel Morel, and Leonard Schulman as Editors-in-Chief.

SIAM Journal on Mathematical Analysis

Arnd Scheel will be the new Editor-in-Chief (EIC) for the SIAM Journal on Mathematical Analysis (SIMA). He will start his three-year term at the end of the year, taking over from Bob Pego of Carnegie Mellon University, who ends two terms as EIC.

Scheel is currently one of SIMA’s five Corresponding Editors, who, along with the Editor-in-Chief make all final decisions, based on recommendations of the Associate Editors and referee reports. This peer-review model was put forth by Pego and has been in place since February 2011, prior to which all final decisions were made by the EIC.

Scheel has previously served as Associate Editor for SIMA, and is currently also an Associate Editor for    the SIAM Journal on Applied Dynamical Systems.

A professor in the School of Mathematics at the University of Minnesota, Scheel’s research interests are in dynamics of partial differential equations, pattern formation, and nonlinear waves.

SIAM Journal on Imaging Sciences

After six years as the first Editor-in-Chief of the SIAM Journal on Imaging Sciences (SIIMS), where he played a visionary role in the journal’s planning, start-up and growth, Guillermo Sapiro of Duke University hands over the reins to Jean-Michel Morel, who will succeed Sapiro on January 1.

Also an original member of the SIIMS Editorial Board, Morel served as an Associate Editor since the journal’s inception in early 2007. A longtime SIAM journals’ author, Morel has also served on the editorial boards of the SIAM Journal on Applied Mathematics and Multiscale Modeling and Simulation.

Morel trained in partial differential equations, variational models and nonlinear analysis. His current research interests are in image analysis and image processing. He is affiliated with the Center for Mathematical Studies and their Applications at ENS Cachan.

SIAM Journal on Computing

Leonard Schulman will succeed Madhu Sudan of Microsoft Research and MIT as Editor-in-Chief of the SIAM Journal on Computing (SICOMP). Sudan has headed the journal since the beginning of 2010, prior to which he served 10 years as an Associate Editor.

Schulman joined the SICOMP board as an Associate Editor in 2010. He is also currently an Associate Editor of the SIAM Journal on Discrete Mathematics.

Schulman has authored papers in SICOMP and SIDMA, and was named guest editor-in-charge of SICOMP’s STOC 2010 Special Section, which will appear upon completion of the review process.

His areas of research interest include algorithms and communication protocols; combinatorics and probability; coding and information theory; and quantum computation.

Mathematics and the Ocean: Movement, Mixing and Climate Modeling

Emily Shuckburgh of the British Atlantic survey uses mathematical ideas from dynamical systems to study mixing in the Southern Ocean

Philadelphia, PA—Studying the dynamics of the ocean system can greatly improve our understanding of key processes of ocean circulations, which have implications for future climate. Can applying mathematics to the research help? Dr. Emily Shuckburgh of the British Antarctic Survey, speaking at the 2012 SIAM Annual Meeting, thinks the answer is an emphatic “yes.”

Dr. Shuckburgh described mathematical ideas from dynamical systems used by her group, along with numerical modeling and experimental observations, to analyze circulation in the Southern Ocean. The Southern Ocean is unique in that it connects three major ocean basins—the Pacific, the Atlantic and the Indian oceans—with a powerful current that circulates all the way around Antarctica. This circumpolar current travels from the North Atlantic, sinking down to the bottom of the ocean and coming up to the surface around Antarctica, thus connecting the deep ocean with the atmosphere above. When water from the deep ocean comes up to the surface, it can exchange heat and carbon dioxide from the atmosphere, thus making it highly significant for climate change.

New NSF Cyber-Enabled Sustainability Program

Last week, the National Science Foundation (NSF) released a solicitation for a new program within the cross-foundational Science, Engineering and Education for Sustainability (SEES) initiative.  Supported by all seven NSF directorates and two offices, the program will fund projects that allow creative interdisciplinary partnerships to address computer and information science challenges that are associated with sustainability.  The goal is to “advance interdisciplinary research in which the science and engineering of sustainability are enabled by new advances in computing, and where computational innovation is grounded in the context of sustainability problems.”

Areas of sustainability that depend in some way on advances in computation can be addressed through the CyberSEES program.  SRC will also provide funding for proposals that address the computational aspects of “smart infrastructure,” particularly the smart electric grid.  Proposals funded by NSF will receive funding through a typical NSF grant, while funding from SRC will be provided through a contract.

Letters of Intent:  Letters of intent are required and due December 4, 2012 and the first Tuesday in December annually.

Due Dates:  Full proposals are due February 5, 2013 and the first Tuesday in February annually.

Total Funding and Award Size:  NSF anticipates making 12 to 20 awards for a total program budget of $12 million, contingent upon final appropriations from Congress.  Proposals are sought at two different levels:
