On the Lie algebra structure of integrable derivations
Benjamin Briggs, Lleonard Rubio y Degrassi
Building on work of Gerstenhaber, we show that the space of integrable derivations on an Artin algebra forms a Lie algebra, and a restricted Lie algebra if contains a field…

Product decompositions of moment-angle manifolds and -rigidity
Steven Amelotte, Benjamin Briggs
A simple polytope is called -rigid if its combinatorial type is determined by the cohomology ring of the moment-angle manifold over . We show that any ten…
