Abstract

Chebyshev polynomials should be well known to the Telecom community through Chebyshev filters. In this talk several forms of the Chebyshev polynomial will be presented, but the focus will be how these polynomials can be used to speed up the solutions of PDEs (Partial Differential Equations). This talk will also include an overview of numerical PDE methods.

Biography

Anne C. Elster was born near the Arctic Circle in Mo i Rana, Norway. After completing her secondary education in Porsgrunn she received a one year scholarship to the Univ. of Oregon, Eugene, OR. Curious to find out how computers really work, she then transferred to the Univ. of Massachusetts at Amherst where she got a B.S. in Computer Systems Engineering with cum laude as well as took several courses in their honors math program. Anne also holds M.S. and Ph.D. degrees in Electrical Engineering from Cornell University where she had a lot of fun at their Supercomputer Center. She is currently a tenured Associate Professor in Computer Engineering and Information Science at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway where she is enjoying a semester focusing on course development, her research on algorithms for telecommunications and parallel environments, as well as pedagogical training. In the past she has served on the MPI standards committee, held summer jobs at CMI, IBM TJ Watson and Xerox Research centers as well as worked for Schlumberger and the Univ. of Texas at Austin. Her husband, Lloyd D. Clark, is an "MIT-cubed" graduate who is one of Schlumberger's primary experts on ADSL-based telemetry.
