SUMMARY:Algebra Seminar
CLASS:PUBLIC
DESCRIPTION:DANIEL HAN\, DEPARTMENT OF PURE MATHEMATICS\, UNIVESITY OF WATE
 RLOO \n\n\"Derived functors and (co)homology theories\"\n\nWe will give a
 n overview of derived functors and their use to form\nhomological invarian
 ts for objects in abelian categories. Using this\nabstract machinery\, we 
 will give rise to group cohomology\, sheaf\ncohomology\, and others. Lastl
 y\, the Eilenberg-Watts theorem will be\npresented to give a loose explana
 tion as to why many of these\ncohomology groups are presented as Ext group
 s.\n\nMC 5479
