### Marvin Knopp: 1933-2011

With great sadness we report that Professor Marvin Knopp passed away December 24 while visiting family in Florida. He joined the Department of Mathematics at Temple in 1976. Prior to coming to Temple he held appointments at the University of Wisconsin, Madison, and the University of Illinois, Chicago. He obtained his Ph.D. in 1958 from the University of Illinois, Urbana-Champaign, under the direction of Paul Bateman. Professor Knopp was born in 1933 in Chicago, Illinois.

Professor Knopp was a leading expert in the theory of Modular Forms, and he twice gave invited addresses to meetings of the American Mathematical Society. He had over 70 publications. In 2007 the International Journal of Number Theory dedicated a volume in his honor.

Over the course of his career Professor Knopp supervised 20 Ph.D. students. He was active mathematically up to the time of his death, and he was supervising the Ph.D. thesis of Austin Daughton, who is currently writing a dissertation based on the research he completed under Professor Knopp's direction.

A brief appreciation, by Professor J. A. Paulos, can be found here.

Memorial activities are being planned.

### Numerical Analysis Day

On November 4 the Department of Mathematics hosted a one-day conference on numerical analysis. The keynote speaker was Lisa Fauci, Pendergraft Nola Lee Haynes Professor of Mathematics, Tulane University. She lectured on "Waving rings and swimming in circles: some lessons learned in biofluiddynamics." The remainder of the talks were given by young researchers: Eighteen graduate students and postdoctoral fellows from Maryland to New York, and from Pittsburgh to Delaware, gave presentations. More details can be found here.

### Marilena Downing, John Schiller, and Daniel Szyld win CST awards

Professor Daniel Szyld won the 2011 CST Dean's Distinguished Award for Excellence in Research. Associate Professor John Schiller and mathematics instructor Marilena Downing each received the Dean's Distinguished Teaching Award. The awards were presented at the annual CST awards banquet, October 30, 2011.

Assistant Professor Benjamin Seibold is PI, and Postdoctoral Research Assistant Professor Prince Chidyagwai is co-PI, on the new NSF Grant Numerical approaches for incompressible viscous flows with high order accuracy up to the boundary. The award is for $299,922. From the abstract: "In many applications in science and engineering, the accurate and efficient computation of forces and stresses at boundaries between fluids and solids is of crucial importance. Examples in which boundary forces (in the form of lift and drag) are key quantities of interest are the design of airplane wings, motor vehicles, and wind turbines, as well as the simulation of sedimentation in stratified fluids and bio-locomotion. The investigators are researching new methodologies and implementations of approaches that allow for a highly accurate computation of these boundary forces." • August, 2011 ### Daniel Szyld and Fei Xue awarded new NSF grant Professor Daniel Szyld is PI, and Postdoctoral Research Assistant Professor Fei Xue is co-PI, on the new NSF grant, Eigenvalues problems, Krylov subspace methods, and subspace recycling. The award is for$280,000. From the abstract: "The problems to be studied in this project include the efficient computation of a group of eigenvalues and the solution of sequences of linear systems. Eigenvalue calculations include analysis of vibration frequencies in structures including buildings, to make sure, for example, that they are far from the earthquake band. Fast algorithms for generalized eigenvalue problems also contribute to the design and analysis of electronic integrated circuit and micro-electro-mechanical systems (MEMS), and the detection of potential presence of turbulent fluid flows. Efficient solution of a sequence of linear systems facilitates modeling of fatigue and fracture via finite element analysis, and the stability analysis of linear systems through the solution of Riccati equations."

### Welcome to new faculty member: Irina Mitrea

Dr. Irina Mitrea joined our department July 1 as Associate Professor. Dr. Mitrea pursued her graduate studies in the School of Mathematics at the University of Minnesota, where she earned a Ph.D. degree under the direction of Carlos Kenig and Mikhail Safonov. Her area of expertise is at the interface between Real and Harmonic Analysis, Partial Differential Equations, and Geometric Measure Theory. Dr. Mitrea's research is currently supported by an NSF CAREER Grant. Other research awards include the 2008 Ruth Michler Memorial Prize from the Association of Women in Mathematics; a Fund for Excellence in Science and Technology Award from the University of Virginia, 2005-2006; a Sloan Dissertation Fellowship, 1999-2000; and a Liftoff Fellowship from the Clay Mathematics Institute, 2000. She currently serves on the Executive Committee of the Association for Women in Mathematics and is an editor for the American Mathematical Monthly.
