A novel algebraic topology approach to supersymmetry (SUSY) and symmetry breaking in
quantum field and quantum gravity theories is presented with a view to developing a wide …

Novel approaches to extended quantum symmetry, paracrystals, quasicrystals,
noncrystalline solids, topological order, supersymmetry and spontaneous, global symmetry …

Let G be a topological locally compact, Hausdorff and second countable groupoid with a
Haar system and K a proper subgroupoid of G with a Haar system too.(G, K) is an internally …

We start from the question raised by Williams (Proc. Am. Math. Soc. 2016): Must a second
countable, locally compact, transitive groupoid G have open range map? If the answer is …
