Among the topics are Lie algebras of special derivation, the

isomorphism problem, and pairings of induced modules.

A new algorithm efficiently solves the graph isomorphism problem, computer scientist Laszlo Babai announced November 10 at a Combinatorics and Theoretical Computer Science seminar at the University of Chicago.

The graph isomorphism problem requires a computer to examine two graphs that may look very different and determine whether all the balls share the same connections.

Among their topics are the

isomorphism problem for Coxeter groups, hyperbolic Coxeter groups and space forms, equivelar polyhedra, configurations of points and lines, and the reciprocal inspiration of Coxeter and artists.

Examples include simultaneous surface resolution in quadratic and biquadratic Galois extensions, asymptotic behavior of cohomology, conic divisor classes over a normal monoid algebra, Rees algebras of the second syzygy module of the residue field of a regular local ring, a local global principle for the elementary unimodular vector group, picture invariants and the

isomorphism problem for complex semisimple Lie algebras, arithmetic rank of certain Segre products, and strong semistability and Hilbert-Kunz multiplicity for singular plane curves.
