Fixed points of condensing multivalued maps in topological vector spaces.
Il est démontré que l’espace des fonctions holomorphes sur un sous-espace homogène , au sens de Katznelson, de muni de la topologie engendrée par les semi-normes portées par les compacts de , est bornologique.
Let K be a compact Hausdorff space, the space of continuous functions on K endowed with the pointwise convergence topology, D ⊂ K a dense subset and the topology in C(K) of pointwise convergence on D. It is proved that when is Lindelöf the -compact subsets of C(K) are fragmented by the supremum norm of C(K). As a consequence we obtain some Namioka type results and apply them to prove that if K is separable and is Lindelöf, then K is metrizable if, and only if, there is a countable and dense...
