A poisonous example to explicit resolutions of unbounded complexes
Dolors Herbera, Wolfgang Pitsch, Manuel Saorín +1
We show that various methods for explicitly building resolutions of unbounded complexes in fact fail when applied to a rather simple and explicit complex. We show that one way to r…
Short incompressible graphs and -free groups
Florent Balacheff, Wolfgang Pitsch
Consider a finite connected -complex endowed with a piecewise Riemannian metric and whose fundamental group is freely indecomposable, of rank at least , and in which ever…
Floyd's manifold is a conjugation space
Wolfgang Pitsch, Jérôme Scherer
We prove that there is an action of the cyclic group on the -dimensional Floyd manifold which turns it into a conjugation manifold. The submanifold of fixed poin…
Some remarks on the Maslov index
Wolfgang Pitsch
It is a classical fact that Wall's index of a triplet of Lagrangians in a symplectic space over a field defines a -cocycle on the associated symplectic group with valu…
Invariants of -Homology 3-Spheres from the Abelianization of the Level-p Mapping Class Group
Ricard Riba, Wolfgang Pitsch
We study the relation between the set of oriented -homology -spheres and the level- mapping class groups, the kernels of the canonical maps from the mapping cla…
Finite quotients of symplectic groups vs mapping class groups
Louis Funar, Wolfgang Pitsch
We give alternative computations of the Schur multiplier of , when is divisible by 4 and : a first one using -theory arguments based on…
