We study when the product of separable metric spaces has the selective screenability property, the Menger property, or the Rothberger property. Our results imply The product of a Lusin set and (1) a Sierpinski set always has the Menger property (Corollary 12); (2) a γ-set always has the Rothberger property (Corollary 13). All topological spaces considered in this paper are assumed to be separab...

Of the several African languages that have become regularly offered at U.S. colleges and universities, Swahili consistently garners the highest enrollments, and is the second most widely taught after Arabic, with the greatest variety of instructional materials compared to its Sub-Saharan African counterparts. According to the Modern Language Association, the number of Swahili-language learners ...

In intuitionistic analysis, a subset of a Polish space like R or N is called positively Borel if and only if it is an open subset of the space or a closed subset of the space or the result of forming either the countable union or the countable intersection of an infinite sequence of (earlier constructed) positively Borel subsets of the space. The operation of taking the complement is absent fro...

My research interest is in mathematical logic and set theory. My current research focuses on studying the connections between inner models, (determined) sets of reals, hybrid structures (such as HOD1 of determinacy models), forcing, and strong combinatorial principles (such as the Proper Forcing Axiom (PFA), (generalizations of) the tree property, the Unique Branch Hypothesis (UBH)). I’m also i...
