## Abstract:

Today, more than fifty years after his death, von Neumann looms larger
than ever as one of the most significant scientists of the 20th
century, one of its greatest mathematicians, a father of the modern
computer and modern computational science, and a prophet of the age of
technology. My twin aim is to paint a picture of the fertility, power,
and sweep of his mind, and to describe how his ideas shaped the
future.

### Research Lecture:* Hyperbolic Partial Differential Equations and Degenerate Matrices*

111 Salmon Library

University of Alabama in Huntsville

## Abstract:

The occurrence of multiple characteristics for hyperbolic
systems gives rise to singularities in solutions. This leads to
topological and algebraic questions about degenerate symmetric matrices and their
discriminant.

## Bio Sketch:

Peter D. Lax, Ph.D, is a very distinguished pure and applied mathematician
who has made significant contributions, ranging from partial differential
equations to applications in engineering. He has made ground breaking
contributions to shock waves, solitons and entropy. His name is connected with many
major mathematical results and numerical methods, such as Lax-Milgram
Lemma, the Lax Equivalence Theorem, the Lax-Friedrichs Scheme, the Lax-
Wendroff Scheme, the Lax Entropy Condition to name a few.
For his outstanding research contributions, spanning half a century, to the
theory and applications of partial differential equations and to the computation
of their solutions, he was
awarded the Abel Prize in 2005 (mathematics equivalent of Nobel prize created by
the Norwegian
Academy of Sciences and letters
http://www.mat.ucm.es/~ln06/lax/abelprize_2005_EN.pdf).
Lax has also served on governing and advisory boards for various government
agencies, academic institutions, and scientific societies.

His other recognitions include,
the National Medal of Science in 1986, presented by President
Ronald Reagan at a White House ceremony, the Wolf Prize in
1987 and the Chauvenet Prize in 1974 and the American Mathematical
Society's Steele Prize in 1992. He was also awarded the Norbert Wiener Prize
in 1975 from the American Mathematical Society and the Society for Industrial
and Applied Mathematics.

He was elected to
the American Philosophical Society (1996),
the Academy of Sciences (Paris) (1982),
the National Academy of Sciences (United States) (1982),
the American Academy of Arts and Sciences (1982),
the New York Academy of Sciences (1982),
the Russian Academy of Sciences (1989),
the Hungarian Academy of Sciences (1993),
Academia Sinica, Beijing (1993),
the Moscow Mathematical Society (1995),
and the London Mathematical Society.
