Fixed Point Sets and the Fundamental Group II: Euler Characteristics
Sylvain Cappell, Shmuel Weinberger, Min Yan
For a group of not prime power order, Oliver showed that the obstruction for a finite CW-complex to be the fixed point set of a contractible finite -CW-complex is the Eu…
Fixed Point Sets and the Fundamental Group I: Semi-free Actions on G-CW-Complexes
Sylvain Cappell, Shmuel Weinberger, Min Yan
Smith theory says that the fixed point of a semi-free action of a group on a contractible space is ${\bb Z}_p$-acyclic for any prime factor of . Jones proved the convers…
Painleve Test and the Resolution of Singularities for Integrable Equations
Jishan Hu, Min Yan
We prove that under a very general setting, a system of ODE passes the Painleve test if and only if there is a good change of variable, such that the pole singularity solutions are…
Extension of Convex Function
Min Yan
We study the local and global versions of the convexity, which is closely related to the problem of extending a convex function on a non-convex domain to a convex function on the c…
Topological Classification of Multiaxial U(n)-Actions
Sylvain Cappell, Shmuel Weinberger, Min Yan
A U(n)-manifold is multiaxial if the isotropy groups are always conjugate to unitary subgroups. The classification and the concordance of such manifolds have been studied by Davis,…
Closed Aspherical Manifolds with Center
Sylvain Cappell, Shmuel Weinberger, Min Yan
We show that in all dimensions >7 there are closed aspherical manifolds whose fundamental groups have nontrivial center but do not possess any topological circle actions. This disp…
