LINEAR ALGEBRA AND ITS APPLICATIONS

Special Issue Honoring Miroslav Fiedler and Vlastimil Ptak

In view of their major contribution to linear algebra and to this

journal, LAA will publish a special issue in honor of

Miroslav Fiedler and Vlastimil Ptak

to mark the occasion of their retirement.

The purpose of this announcement is to solicit papers for this issue.

The deadline for submission is 30 August 1993 and the issue is expected

to appear about 15 months later.

Papers are invited concerning any aspect of linear algebra, its

applications, and its interactions with graph theory or functional

analysis. All contributions will be subject to the normal reviewing

process.

Submissions should be sent to one of the special editors of this

issue:

INSTITUTE FOR MATHEMATICS AND ITS APPLICATIONS

POSTDOCTORATES IN INDUSTRIAL MATHEMATICS

IMA announces at least 4 one-to-two year positions in

Industrial Mathematics, effective September 1, 1993. These

appointments are in addition to the regular program and are

funded jointly by the NSF and participating industries. They

are designed to prepare mathematicians for research careers

involving industrial interaction. Applicants should have

fulfilled all requirements for a Ph.D. in Mathematics or

Applied Mathematics by September 1, 1993. Familiarity with pde

and/or numerical analysis is desired, but no knowledge in

engineering is required. Postdoctorates* will spend 50% effort

working with industrial scientists on one of the following

topics: (1) Signal processing and computational ocean

acoustics; (2) Diffractive optics; Maxwell equations in

periodic structure; (3) Computational fluid mechanics; (4)

Scattering of electromagnetic waves from complex objects; (5)

Magneto-optic recording media; the writing process; (6)

Semiconductors; (7) Solid state physics & computational

chemical physics; (8) Problems in mathematical photography; (9)

Air quality modeling; (10) Control theory; (11) Imaging

analysis; (12) Micromagnetics; (13) Near-infrared imaging; (14)

Applied statistical information theory and data fusion; and

50% effort in the regular IMA program.

The following materials must be submitted (all material

should arrive by January 15, 1993):

(1) Personal statement of scientific interests, research plans,

and reasons for wishing to participate in the Industrial

Postdoc program. (This is an essential part of the application.)

(2) Curriculum vitae and a list of publications.

(3) Three letters of recommendation, to be sent directly to the

IMA.

*The actual hiring title will be ``Research Associate''.

The University of Minnesota is an equal opportunity educator

and employer.

The application forms are available via anonymous ftp:

**Subject: Positions at University of Colorado**

POSITIONS AT UNIVERSITY OF COLORADO, BOULDER

The University of Colorado has been awarded a 5-year $4.5M NSF Grand

Challenge Applications Groups award in High Performance Computing. The

research will focus on three related areas: interactions of structures and

fluids (e.g. aerodynamics), turbulence in geophysical and astrophysical

environments, and computer science areas related to HPCC.

Several post-doctoral positions are available immediately in Computer

Science for qualified applicants. We also encourage applications for next

year and from prospective HPC graduate students in Computer Science. Success-

ful candidates will not necessarily have computer science backgrounds, but

must have experience and interest in one or more of parallel computing (per-

formance analysis, program transformation and parallelization, heterogeneous

computing, fluid dynamic applications), scientific databases or visualization,

and must be interested in pursuing these activities from a computer science

perspective. Research will occur in a multi-disciplinary environment consist-

ing of computer scientists, physical scientists and engineers.

Applications and letters of recommendation should be sent to:

Dr. Oliver McBryan,

Dept. of Computer Science,

University of Colorado,

Boulder, CO 80309.

mcbryan@cs.colorado.edu

The University of Colorado at Boulder has a strong institutional commit-

ment to the principle of diversity in all areas. In that spirit, we are par-

ticularly interested in receiving applications from a broad spectrum of peo-

ple, including women, members of ethnic minorities, and disabled individuals.
