Deterministic polynomial identity testing
WebDevising an efficient deterministic – or even a non-deterministic sub-exponential time – algorithm for testing polynomial identities is a fundamental problem in alge-braic complexity and complexity at large. Motivated by this problem, as well as by results from proof complexity, we investigate the complexity of proving polynomial identities. WebIdentity Testing for polynomials given as arithmetic formulas over Z (or even circuits, by Prob- ... (i.e. a sum of terms, each of which is the product of linear functions in the input variables). A deterministic polynomial-time algorithm for formulas where the outermost sum has only a constant number of terms was obtained quite recently (2005).

Prior to this work, sub-exponential time deterministic … Webdeterministically, given a deterministic algorithm for the polynomial identity testing problem (we require either a white-box or a black-box algorithm, depending on the representation of f). Together with the easy observation that deterministic factoring implies a deterministic algo-rithm for polynomial identity testing, this establishes an ...

In this work, we study the complexity of two special but natural cases of identity testing—first is a case of depth-3 PIT, the other of depth-4 PIT.Our first problem is a vast generalization of verifying whether a bounded top …
Webdeterminant polynomial (on dn dnmatrices). The alert reader will have noticed that in the commutative PIT problem, singularity is captured by a single polynomial identity, namely the case d= 1 above! Somehow, testing if a given tuple of matrices satisfies the infinite system of identities above seems now easier than testing the single one ...
