From Heegaard diagrams to surgery
Jovana Nikolic, Vuk Ovaskainen, Zoran Petric
A procedure of going from Heegaard diagrams to framed link diagrams is explained in this note.
A diagrammatic presentation of the category 3Cob
Jovana Nikolic, Zoran Petric, Mladen Zekic
A category equivalent to the category of 3-dimensional cobordisms is defined in terms of planar diagrams. The operation of composition in this category is completely described via…
A calculus for S^3-diagrams of manifolds with boundary
Bojana Femic, Vladimir Grujic, Jovana Obradovic +1
We introduce a diagrammatic language for compact, orientable 3-dimensional manifolds with boundary. A diagrammatic calculus (both integral and rational version) appropriate for thi…
Coherence for closed categories with biproducts
Zoran Petric, Mladen Zekic
A coherence result for symmetric monoidal closed categories with biproducts is shown in this paper. It is explained how to prove, by using the same technique, coherence for compact…
Proofs and surfaces
Djordje Baralic, Pierre-Louis Curien, Marina Milicevic +4
A formal sequent system dealing with Menelaus' configurations is introduced in this paper. The axiomatic sequents of the system stem from 2-cycles of Delta-complexes. The Euclidean…
A simple permutoassociahedron
Djordje Baralic, Jelena Ivanovic, Zoran Petric
In the early 1990s, a family of combinatorial CW-complexes named permutoassociahedra was introduced by Kapranov, and it was realized by Reiner and Ziegler as a family of convex pol…
