SUMMARY:Algebraic Geometry Seminar
CLASS:PUBLIC
DESCRIPTION:CATHERINE ST-PIERRE\, UNIVERSITY OF WATERLOO\n\nSheppard-Todd-C
 hevalley theorem (and beyond)\n\nSheppard-Todd-Chevalley's theorem is one 
 of the most significant\nresults in invariant theory. It provides necessar
 y and sufficient\nconditions for the fixed subring k[x_1\, \\dots \, x_n]^
 G under a finite\nsubgroup G of GL_n(k) to be a polynomial ring. We will r
 eview the\ntheorem and its applications and summarise some generalisations
