EULER CHARACTERISTICS FOR SPACES OF STRING LINKS AND THE MODULAR ENVELOPE OF L-infinity
Homology, Homotopy and Applications(2018)
摘要
We make calculations in graph homology which further understanding of the topology of spaces of string links, in particular, calculating the Euler characteristics of finite-dimensional summands in their homology and homotopy. In doing so, we also determine the supercharacter of the symmetric group action on the positive arity components of the modular envelope of L-infinity.
