- Title
COHOMOLOGICAL INVARIANTS OF MAPPING CLASS GROUPS.
- Authors
PRIDDY, STEWART; XIA, YINING
- Abstract
The article discusses a series of cohomological integral invariants of mapping class groups, which is defined as the group of path components of orientation preserving diffeomorphisms of an oriented closed surface. It states that the calculation of integral invariants can be done by using some representational and geometric methods for the mapping class groups. Also, it presents geometric representation the Krull dimension, which does not agree with the calculation from the spetral sequence.
