In this paper, we study irreducible modules over the mirror Heisenberg–Virasoro algebra D 𝔇, which is the semi-direct product of the Virasoro algebra and the twisted Heisenberg algebra. We classify ...

This note demonstrated that a certain class of Petri nets called timed-event multigraphs can be represented as a set of linear equations by using a novel dioid. With this new algebra, some properties ...
