Marina **Semenova***Closure lattices of closure spaces and their elementary properties*

Abstract:

Given a closure space, we are interested in elementary
properties of the corresponding lattice of closed
subsets (closure lattice, in other words). In
particular, we are interested in the structure of the
quasivariety generated by closure lattices of some
certain closure spaces. In some particular cases that
quasivariety turns out to be a variety.
