Query: Tense operators on m-symmetric algebras   Here we initiate an investigation of the equational classes of m-symmetric
algebras endowed with two tense operators. These varieties is a generalization
of tense algebras. Our main interest is the duality theory for these classes of
algebras. In order to do this, we require Urquart's duality for Ockham algebras
and Goldblatt's duality for bounded distributive lattice with operations. The
dualities enable us to describe the lattices of congruences on tense
m-symmetric algebras.
