On some dicardinal functionsin ditopological texture spaces : Open Mathematics

摘要

In the paper we show that net weight and conet weight equal each other in any complemented ditopologicalspace, and investigate under which conditions pseudo character and copseudo character equal each other. We givesome important results “bounding" the set Q of all q-sets in (a particular subclass of) the class of all ditopologicaltexture spaces.
