Abstract: This article studies the properties of various subclasses of weakly dyadic compact spaces. We prove that each weakly dyadic compact space is a strictly $a$-space. We also show that the product of a compact space and a Corson compact space without isolated points is a strictly $a$-space.

Keywords: condensation, $a$-space, strictly $a$-space, weakly dyadic space, thick space.
