On Efficient Noncommutative Polynomial Factorization via Higman Linearization
V. Arvind, Pushkar S. Joglekar
In this paper we study the problem of efficiently factorizing polynomials in the free noncommutative ring F of polynomials in noncommuting variables x1,x2,...,xn over the field F.…

On a Hierarchy of Spectral Invariants for Graphs
V. Arvind, Frank Fuhlbrück, Johannes Köbler +1
We consider a hierarchy of graph invariants that naturally extends the spectral invariants defined by Fürer (Lin. Alg. Appl. 2010) based on the angles formed by the set of standar…
