Variations of star selection principles on Hyperspaces
, 2023 In this paper we define some combinatorial principles to characterize spaces $X$ whose hyperspace satisfies some variation of some classical star selection principle.

The (dis)connectedness of products in the box topology
, 2013 We suggest two independent sufficient conditions on topological connected spaces with axioms lower than $T_3$, which imply disconnectedness, and one sufficient condition, which implies connectedness, of products of spaces endowed with the box topology.

Topology of utility possibility frontiers of economies with Ramsey taxation [PDF]
This paper establishes the generic size and structure of the second-best Pareto frontier and its various components in private ownership economies with Ramsey taxation. It provides conditions under which the second-best Pareto frontier of an economy with

Hyperspaces in the theory of function spaces
, 1971 In this paper certain topics involving the role played by spaces of subsets in the theory of function spaces are studied. After recalling some properties of spaces of set-valued functions a space, [cursive I[raised infinity, lowered X]], which may be ...

Sets with the Baire property in topologies formed from a given topology and ideals of sets
, 2017 Let X be a set, τ1, τ2 topologies on X and Bp(X, τi) the family of all subsets of X possessing the Baire property in (X, τi), i = 1, 2. In this paper we study conditions on τ1 and τ2 that imply a relationship (for example, inclusion or equality) between ...
