Faculty research interests

Judith Roitman'searly work focused on problems related to S and L spaces and on paracompact box products. In the 1990's she focused on Boolean algebras. The topological spaces she looked at tend to be closely related to Stone spaces of Boolean algebras. Her work centered on homomorphisms/continuous maps, and on canonical examples such as Ostaszewski spaces and Kunen lines. These two areas a not unrelated. More recently she was interested in almost disjoint families of integers and the Boolean algebras they generate, and (with Fleissner and Porter) connected subtopologies of Hausdorff spaces. More recently she has returned to the problem of paracompact box products.
