SUMMARY:Geometry Working Seminar
CLASS:PUBLIC
DESCRIPTION:ANDREW STAAL\, DEPARTMENT OF PURE MATHEMATICS\, UNIVERSITY OF W
 ATERLOO\n\n\"Reducibility of Varieties of Commuting Matrices\"\n\nWe will 
 present some well-known results on reducibility of the\nvarieties C(k\,n) 
 of commuting k-tuples of nxn-matrices.  In\nparticular\, we will discuss 
 the Motzkin—Taussky Theorem proving\nirreducibility of C(2\,n) and Gural
 nick’s Theorem\, which shows that\nC(3\,n) is reducible when n ≥ 29.
