Effective topological complexity of orientable-surface groups

چکیده
We use rewriting systems to spell out cup-products in the (twisted) cohomology groups of a product surface groups. This allows us detect non-trivial obstruction bounding from below effective topological complexity an orientable with respect its antipodal involution. Our estimates are at most one unit being optimal, and closely related (regular) non-orientable surfaces.

Topological Complexity of Basis-conjugating Automorphism Groups
We compute the topological complexity of Eilenberg-MacLane spaces associated to the group of automorphisms of a finitely generated free group which act by conjugation on a given basis, and to certain subgroups.
متن کاملEnumerating branched orientable surface coverings over a non-orientable surface
The isomorphism classes of several types of graph coverings of a graph have been enumerated by many authors [M. Hofmeister, Graph covering projections arising from finite vector space over finite fields, Discrete Math. 143 (1995) 87–97; S. Hong, J.H. Kwak, J. Lee, Regular graph coverings whose covering transformation groups have the isomorphism extention property, Discrete Math. 148 (1996) 85–1...

متن کاملL-FUZZIFYING TOPOLOGICAL GROUPS
The main purpose of this paper is to introduce a concept of$L$-fuzzifying topological groups (here $L$ is a completelydistributive lattice) and discuss some of their basic properties andthe structures. We prove that its corresponding $L$-fuzzifyingneighborhood structure is translation invariant. A characterizationof such topological groups in terms of the corresponding$L$-fuzzifying neighborhoo...
