Query: Dualities for Plonka sums   Plonka sums consist of an algebraic construction similar, in some sense to
direct limits, which allows to represent classes of algebras defined by means
of regular identities (namely those equations where the same set of variables
appears on both sides). Recently, Plonka sums have been connected to logic, as
they provide algebraic semantics to logics obtained by imposing a syntactic
filter to given logics. In this paper, I present a very general topological
duality for classes of algebras admitting a Plonka sum representation in terms
of dualisable algebras.
