✦ Synopsis

We extend the enumeration of regular linear spaces in [1] to at most 19 points. In addition, one of the 5 missing cases in the previous list is settled. The number of regular linear spaces of type ð15j2 15 ; 3 30

Complete L-regularity is internally characterized in terms of separating chains of open L-sets. A possible characterization in terms of normal and separating families of closed L-sets is discussed and it is shown that spaces admitting such families are completely L-regular. The question of whether t

## Abstract We prove, in ZFC alone, some new results on regularity and decomposability of ultrafilters; among them: (a) If __m__ ≥ 1 and the ultrafilter __D__ is (~__m__~(__λ__^+__n__^), ~__m__~(__λ__^+__n__^))‐regular, then __D__ is __κ__ ‐decomposable for some __κ__ with __λ__ ≤ __κ__ ≤ 2^__λ__^

## Abstract We present bounded positivity preserving operators from __L__~__p__~(ℝ) to __L__~__q__~ (__ℝ__), for 1 < __p__ < ∞, 1/p‐1/q < 1/2, which are not integral operators.
