✦ Synopsis

In this paper we answer questions of Arhangel'skii and Michael by providing an example of a regular symmetrizable spslce which is not subparacompact and has a closed subset which is not a C&set. We also use the idea of sequential arder to obtain some positive results, and several examples are provided wfsicb show that these results are in some sense the best possible.

## Abstract We study contractive, existence and optimal sets in modular spaces. We define the analogous classes of sets with respect to a modular and generalize a number of results due to Beauzamy and Maurey [3] and Bruck [9] to modular spaces. We then apply them to show that in certain Köthe seque

We investigate C-compact and relatively pseudocompact subsets of Tychonoff spaces with a special emphasis given to subsets of topological groups. It is shown that a relatively pseudocompact subset of a space X is C-compact in X, but not vice versa. If, however, X is a topological group, then these p
