The main result of this paper shows how coalgebraic traces, in suitable Kleisli categories, give rise to traced monoidal structure in those Kleisli categories, with finite coprodu...
We describe a metalanguage MMML, which makes explicit the order of evaluation (in the spirit of monadic metalanguages) and the staging of computations (as in languages for multi-l...
We present an algebraic treatment of exception handlers and, more generally, introduce handlers for other computational effects representable by an algebraic theory. These include ...
