Countably P-Concentrative Pairs and the coincidence index
In this paper, a new coincidence index is presented for countably P-concentrative pairs. 1. INTRODUCTION Let X and Y be metric spaces. A continuous single valued map p : Y-* X is called a Vietoris map [1,2] if the following two conditions are satisfied: (i) for each x E X, the set p-l(x) is acyclic, (ii) p is a proper map, i.e., for every compact A C X we have that p-l(A) is compact. Let D(X, Y...
متن کاملDirac-harmonic maps from index theory
We prove existence results for Dirac-harmonic maps using index theoretical tools. They are mainly interesting if the source manifold has dimension 1 or 2 modulo 8. Our solutions are uncoupled in the sense that the underlying map between the source and target manifolds
متن کاملP Points with Countably Many Constellations
If the continuum hypothesis (CH) is true, then for any P point ultrafilter D (on the set of natural numbers) there exist initial segments of the Rudin-Keisler ordering, restricted to (isomorphism classes of) P points which lie above D, of order type N,. In particular, if D is an RK-minimal ultrafilter, then we have (CH) that there exist P-points with countably many constellations. 0. Introducti...
متن کاملCountably Admissible Numbers and Linear Category Theory
Suppose Hadamard’s criterion applies. In [2], the authors address the existence of arrows under the additional assumption that every ultraconvex equation is independent. We show that B is geometric. It would be interesting to apply the techniques of [32] to reducible functionals. In contrast, the groundbreaking work of A. Wilson on functors was a major advance.
