On the Hardness of Order Finding and Equivalence Testing for ROABPs

C. Ramya, Pratik Shastri

The complexity of representing a polynomial by a Read-Once Oblivious Algebraic Branching Program (ROABP) is highly dependent on the chosen variable ordering. Bhargava et al. prove…

Efficient Polynomial Identity Testing Over Nonassociative Algebras

Partha Mukhopadhyay, C Ramya, Pratik Shastri

We design the first efficient polynomial identity testing algorithms over the nonassociative polynomial algebra. In particular, multiplication among the formal variables is commuta…

Lower bounds for planar Arithmetic Circuits

C. Ramya, Pratik Shastri

Arithmetic circuits are a natural well-studied model for computing multivariate polynomials over a field. In this paper, we study planar arithmetic circuits. These are circuits who…

On Identity Testing and Noncommutative Rank Computation over the Free Skew Field

V. Arvind, Abhranil Chatterjee, Utsab Ghosal +2

The identity testing of rational formulas (RIT) in the free skew field efficiently reduces to computing the rank of a matrix whose entries are linear polynomials in noncommuting va…

On Finer Separations between Subclasses of Read-once Oblivious ABPs

C. Ramya, Anamay Tengse

Read-once Oblivious Algebraic Branching Programs (ROABPs) compute polynomials as products of univariate polynomials that have matrices as coefficients. In an attempt to understand…

If VNP is hard, then so are equations for it

Mrinal Kumar, C. Ramya, Ramprasad Saptharishi +1

Assuming that the Permanent polynomial requires algebraic circuits of exponential size, we show that the class VNP does not have efficiently computable equations. In other words, a…
