Contact Courant algebroids and -algebras
Apurba Das
Let be a line bundle over . In this paper we associate an -algebra to any -Courant algebroid (contact Courant algebroid in the sense of Grabowski). This constru…
Crossed extensions of Lie algebras
Apurba Das
It is known that Hochschild cohomology groups are represented by crossed extensions of associative algebras. In this paper, we introduce crossed -fold extensions of a Lie algebr…
Hom-associative algebras up to homotopy
Apurba Das
A hom-associative algebra is an algebra whose associativity is twisted by an algebra homomorphism. In this paper, we introduce a strongly homotopy version of hom-associative algebr…
Enumerating Top-k Quasi-Cliques
Seyed-Vahid Sanei-Mehri, Apurba Das, Srikanta Tirthapura
Quasi-cliques are dense incomplete subgraphs of a graph that generalize the notion of cliques. Enumerating quasi-cliques from a graph is a robust way to detect densely connected st…
Homotopy G-algebra structure on the cochain complex of hom-type algebras
Apurba Das
A hom-associative algebra is an algebra whose associativity is twisted by an algebra homomorphism. We show that the Hochschild type cochain complex of a hom-associative algebra car…
Shared-Memory Parallel Maximal Clique Enumeration
Apurba Das, Seyed-Vahid Sanei-Mehri, Srikanta Tirthapura
We present shared-memory parallel methods for Maximal Clique Enumeration (MCE) from a graph. MCE is a fundamental and well-studied graph analytics task, and is a widely used primit…
