Charles M. Steinberg (1932–99)

Profile of Charles M. Newman.

O n the surface, CharlesNewman’s mathematical research looks abstract, but his models are never far from potential application to the real world. Newman specializes in models of disordered systems that condensed-matter physicists use to understand the behavior of materials as they change phases. His work has also provided insight into apparent discontinuities in the fossil record and the potent...

The Steinberg Tensor Product Theorem for GL(m|n)

The Steinberg Tensor Product Theorem is a fundamental result in the modular representation theory of algebraic groups. The purpose of the present article is to formulate and prove the analogous theorem for the supergroup GL(m|n). This result was first mentioned without proof in [2]. We emphasize that our approach closely parallels the analogous result for the supergroup Q(n) proven by Brundan a...

Charles Bonnet, Lettres à M. l'Abbé Spallanzani

when Davis et al. in 1962, demonstrated the breakdown of ATP in a single tetanic contraction of a muscle treated with l-fluoro-2, 4-dinitrobenzene. Chapter 15 is devoted to rigor mortis. Preceded by chapters on the general history of respiration (Chapter 16) and of oxidative phosphorylation (Chapter 17), Chapter 18 is concerned with the regulation of carbohydrate metabolism for energy supply to...

The Steinberg Representation

Introduction. Group representations occupy a sort of middle ground between abstract groups and transformation groups, i.e., groups acting in concrete ways as permutations of sets, homeomorphisms of topological spaces, diffeomorphisms of manifolds, etc. The requirement that the elements of a group act as linear operators on a vector space limits somewhat the complexity of the action without sacr...
