Solutions for the quasi-Yang-Baxter equation. Diagrammatics, axioms and semi-classical approximations
Gefry Barad
We generalize Nichita, Popovici and Tanasa solutions of the Braid equation to quasi-Yang-Baxter equation. We define quasi-braided Lie algebras in an additive monoidal category as a…

Non-trivial 1-classes in the homology of the real moduli spaces M-bar_{0,n} and related structures
Gefry Barad
We give lower bounds for the rank of the first homology group of the real points of the Deligne-Mumford-Knudsen compactification of stable n-pointed curves of genus 0,which coincid…

The Homology of the real moduli spaces \bar(M)_(0,n)
Gefry Barad
We compute the rank of the first homology group and we study the higher Betti numbers of the real points of the Deligne-Mumford-Knudsen compactification of stable n-pointed curves…
