Monadic Monadic Second Order Logic

open access: yes, 2023
One of the main reasons for the correspondence of regular languages and monadic second-order logic is that the class of regular languages is closed under images of surjective letter-to-letter homomorphisms. This closure property holds for structures such as finite words, finite trees, infinite words, infinite trees, elements of the free group, etc ...

The Vietoris Monad and Weak Distributive Laws [PDF]

open access: yesApplied Categorical Structures, 2018
The Vietoris monad on the category of compact Hausdorff spaces is a topological analogue of the power-set monad on the category of sets. Exploiting Manes’ characterisation of the compact Hausdorff spaces as algebras for the ultrafilter monad on sets, we ...

On $\ast$-measure monads on the category of ultrametric spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022

Quantifiers on languages and codensity monads [PDF]

open access: yes, 2017
This paper contributes to the techniques of topo-algebraic recognition for languages beyond the regular setting as they relate to logic on words. In particular, we provide a general construction on recognisers corresponding to adding one layer of various

Probability monads as codensity monads

open access: yesTheory and Applications of Categories, 2022
We show from a categorical point of view that probability measures on certain measurable or topological spaces arise canonically as the extension of probability distributions on countable sets. We do this by constructing probability monads as the codensity monads of functors that send a countable set to the space of probability distributions on that ...

Heterotic instantons for monad and extension bundles [PDF]

open access: yesJournal of High Energy Physics, 2019
We consider non-perturbative superpotentials from world-sheet instantons wrapped on holomorphic genus zero curves in heterotic string theory. These superpotential contributions feature prominently in moduli stabilization and large field axion inflation ...

Weak Completeness of Coalgebraic Dynamic Logics [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
We present a coalgebraic generalisation of Fischer and Ladner's Propositional Dynamic Logic (PDL) and Parikh's Game Logic (GL). In earlier work, we proved a generic strong completeness result for coalgebraic dynamic logics without iteration.

Combinatorial structure of type dependency [PDF]

open access: yes, 2014
We give an account of the basic combinatorial structure underlying the notion of type dependency. We do so by considering the category of all dependent sequent calculi, and exhibiting it as the category of algebras for a monad on a presheaf category. The
