In this paper,we prove the non-triviality of the product h 0 k o δ s+4 ∈ Ext s+6,t(s) A (Z p ,Z p ) in the classical Adams spectral sequence,where p ≥ 11,0 ≤ s p-4,t(s) = (s + 4)p 3 q + (s + 3)p 2 q...

In this paper,we introduce the concept of weakly KKM map on an abstract convex space without any topology and linear structure,and obtain Fan's matching theorem and intersection theorem under very weak assumptions on...

Based on a KKM type theorem on FC-space, some new fixed point theorems for Fan-Browder type are established, and then some collectively fixed point theorems for a family of Ф-maps defined on product space of FC-space...
