Iteration semigroups with generalized convex, concave and affine elements.
The weak convergence of the iterative generated by , , to a coincidence point of the mappings is investigated, where is a real reflexive Banach space and its dual (assuming that is strictly convex). The basic assumptions are that is the duality mapping, is demiclosed at , coercive, potential and bounded and that there exists a non-negative real valued function such that
Ram’ırez-Páramo proved that under GCH for the class of compact Hausdorff spaces i-weight reflects all cardinals [A reflection theorem for i-weight, Topology Proc. 28 (2004), no. 1, 277–281]. We show that in ZFC i-weight reflects all cardinals for the class of compact LOTS. We define local i-weight, then calculate i-weight of locally compact LOTS and paracompact spaces in terms of the extent of the space and the i-weight of open sets or the local i-weight. For locally compact LOTS we find a necessary...
