Two polynomials f, g ∈ F[x1, . . . , xn] over a field F are said to be equivalent if there exists an n×n invertible matrix A over F such that g = f(Ax), where x = (x1 · · · xn)T . The equivalence test (in short, ET) for ...

Understanding the structure and complexity of a polynomial family is a fundamental problem of arithmetic circuit complexity. There are various approaches like studying the lower bounds, which deals with nding the smallest ...
