DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/49/">Ma
 ssey Products for Graph Homology.</a>\nby Benjamin Ward (BGSU) as part of 
 Geometry and topology online\n\n\nAbstract\nThis talk is about graph compl
 exes and their homology.  A graph complex can be thought of as a generaliz
 ation of a dg associative algebra\, but with more sophisticated compositio
 n operations allowing for particles to collide along any graph\, not just 
 along a line.  Is every graph complex quasi-isomorphic to its homology?  C
 ontinuing the analogy with associative algebras the answer is no\, but we 
 will see how an A-infinity analog of graph complexes can be used to rectif
 y this situation.  We will then discuss what these higher operations can t
 ell us in the particular cases of Lie and commutative graph homology.\n
