APPM Department Colloquium - Dongbin Xiu

April 27, 2007

Event Description: Dongbin Xiu, Department of Earth And Atmospheric Sciences, Purdue University Efficient methods for numerical simulations with uncertainty Most of the research efforts in scientific computing so far have been in developing efficient algorithms for different applications, assuming ideal inputs with precisely defined computational domains. Recently, there has been...

APPM Department Colloquium - Webster Cash

April 20, 2007

Event Description: Webster Cash, Department of Astrophysical and Planetary Scienes (APS), University of Colorado Boulder Struggling with the mathematics of diffraction and the search for life in the universe Our best hope of finding evidence of life in the Universe is to study the Earth-like planets around nearby stars. Spectra...

APPM Department Colloquium - Natasha Flyer

April 13, 2007

Event Description: Natasha Flyer, Institute for Mathematics Applied to Geosciences (IMAGe), NCAR Modeling simple atmospheric flows on the sphere using radial basis functions Since the early 1990s, radial basis functions (RBFs) have been applied to solve simple elliptical and mixed parabolic partial differential equations (PDEs). Not until 2003 was the...

APPM Department Colloquium - Bengt Fornberg

April 6, 2007

Event Description: Bengt Fornberg, Department of Applied Mathematics, CU Boulder Radial basis functions for solving PDEs - some recent developments Radial basis functions (RBFs) originated in the 1970s as a method for interpolating scattered data. More recently, both our knowledge about RBFs and their range of applications have grown tremendously...

APPM Department Colloquium - Sheldon Newhouse

April 6, 2007

Event Description: Sheldon Newhouse, Department of Astrophysical and Planetary Scienes (APS), University of Colorado Boulder What we do and do not know about simple dynamical systems It is well-known that simple dynamical systems can have complicated orbit structures. We describe some recent progress in understanding the structures of polynomial maps...

APPM Department Colloquium - Nathan C. Thompson

March 21, 2007

Event Description: Nathan C. Thompson, CEO & Founder of Spectra Logic Corporation From Numerical Analysis to the Numerical Boardroom This highly interactive presentation will trace the 24 year business history of Nathan Thompson from being one of Dr. Curry’s first students as a young mathematics professor at the University of...

APPM Department Colloquium - Peter D. Lax

March 9, 2007

Event Description: Peter D. Lax, Courant Institute of Mathematial Sciences, New York University Mathematics and physics are different enterprises; physics is looking for the laws of nature, mathematics is trying to invent the structures and prove the theorems of mathematics. The two endeavors have nevertheless always been closely linked. In...

APPM Department Colloquium - Leslie Greengard

March 2, 2007

Event Description: Leslie Greengard, Courant Institute of Mathematical Sciences, Ney York University 100 years of electromagnetic waves: physics, simulation, and design We will review the analytic and computational foundations of Green’s function based methods for electromagnetic scattering, including high order integral representations, fast solvers, and quasi-periodicity. We will then discuss...

APPM Department Colloquium - Ken Miller

Feb. 23, 2007

Event Description: Ken Miller, Department of Mathematics, Wichita State University Steady axisymmetric vortex flows Steady axisymmetric vortex flows both with and without swirl will be discussed. Existence theorems for the non-linear partial differential equations that model such flows, as well as an iterative numerical method for computing then, will be...

APPM Department Colloquium - Jean Hertzberg

Feb. 16, 2007

Event Description: Jean Hertzberg, Department of Mechanical Engineering, University of Colorado Boulder Beautiful physics from ordinary fluids Household fluids are capable of illustrating sublime physics, using very simple setups. Students in engineering and fine arts, enrolled in a course on flow visualization at the University of Colorado, have employed common...
