A colored graph is a complete graph in which a color has been assigned to each edge, and a colorful cycle is a cycle in which each edge has a different color. We first show that a…
Categorical Geometry and Integration Without Points
Igor Kriz, Ales Pultr
The theory of integration over infinite-dimensional spaces is known to encounter serious difficulties. Categorical ideas seem to arise naturally on the path to a remedy. Such an ap…
A Universal Approach to Vertex Algebras
Ruthi Hortsch, Igor Kriz, Ales Pultr
We characterize vertex algebras (in a suitable sense) as algebras over a certain graded co-operad. We also discuss some examples and categorical implications of this characterizati…
Dualities and dual pairs in Heyting algebras
Jan Foniok, Jaroslav Nesetril, Ales Pultr +1
We extract the abstract core of finite homomorphism dualities using the techniques of Heyting algebras and (combinatorial) categories.
