Symposium on Inverse Problems: Geophysical Applications

Conducted by SIAM with the cooperation of Gesellschaft fur Angewandte Mathematik und Mechanik (GAMM)
December 16-19, 1995
Marriott Tenaya Lodge at Yosemite
Fish Camp, California


This symposium is the second of a series of symposia on inverse problems and their applications. The first symposium held June 27-July 1, 1994 in St. Wolfgang, Austria focused on applications in diffusion processes. The second symposium will focus on the study of connections of gravitational, seismic, electromagnetic, and thermal fields, with the structure of our planet. These fields may be of natural origin, such as oscillations caused by earthquakes and telluric currents, or they may be induced as in seismic prospecting and geophysical prospecting by electrical means. The interpretation of geophysical data leads to inverse problems, i.e. from physical laws and the data of field measurements determine the characteristics of the medium.

The purpose of this symposium is to encourage interdisciplinary interaction among practitioners and theoreticians, with a focus on inverse problems of interest to science and industry. The development and applications of powerful computational and mathematical tools will be highlighted.

The symposium will take place at the Marriott's Tenaya Lodge -- a new world-class hotel surrounded by thousands of acres of national forest, and just minutes from the southern entrance to Yosemite Park. Tenaya Lodge allows you to visit Yosemit e Park's Sierra Nevada. Miles of trails await the hiker and horseback rider; wagon rides with campfires; and downhill and cross-country skiing. There is something for everyone, and the scenery promises to be breathtaking. Yosemite is approximately a 4-hour drive from San Francisco, and a 1-hour shuttle ride from Fresno.

Symposium Themes

Who Will Attend?

The symposium will attract engineers, mathematicians, and scientists from universities, industry, and government who are engaged in research in geophysics.

Organizing Committee

Heinz W. Engl (Co-chair)
Institut fur Mathematik
Johannes-Kepler Universitat, Austria

William Rundell (Co-chair)
Department of Mathematics
Texas A&M University, College Station

David L. Colton
Department of Mathematical Sciences
University of Delaware

Alfred Louis

(One-hour plenary talks)

Symposium Format

The symposium will be run in a workshop-like atmosphere. Each half-day will be highlighted by an hour plenary address followed by three or four related 30-minute presentations. This format will allow the results on recent research to be communicated and still allow ample time for discussion and interaction. An evening session of contributed papers will allow attendees, particularly student s and young researchers, to discuss their research in a relaxed atmosphere.

How to Contribute

Contributed presentations in lecture format are invited in all areas of geophysics consistent with the symposium themes. A lecture format involves a 25-minute oral presentation with an additional five minutes for discussion. Contributors must submit a brief, 75-word abstract on a SIAM abstract form. To help in formatting your submission, plain TeX or LaTeX macros are available by sending your request to

Deadline for submission of contributed abstracts: MAY 19, 1995.
