We study the problem of expressing permanents of matrices as determinants of (possibly larger) matrices. This problem has close connections to the complexity of arithmetic computations: the complexities of computing permanent and determinant roughly correspond to arithmetic versions of the classes NP and P respectively. We survey known results about their relative complexity and describe two recently developed approaches that might lead to a proof of the conjecture that the permanent can only… 

Permanent vs. Determinant

A major problem in theoretical computer science is the Permanent vs. Determinant problem. It asks: given an n by n matrix of indeterminates A = (ai,j) and an m by m matrix B with entries that are

AN UPPER BOUND FOR THE PERMANENT VERSUS DETERMINANT PROBLEM

The Permanent versus Determinant problem is the following: Given an n × n matrix X of indeterminates over a field of characteristic different from two, find the smallest matrix M whose coefficients

Determinantal Complexities and Field Extensions

TLDR
This paper states that the determinantal complexity of the permanent polynomial is the smallest size of a matrix M whose entries are linear polynomials of x i ’s over \(\mathbb{F}\), such that P=det (M) as polynmials in \(\mathBB{F}[x_1, \dots, x_n]\).

A Case of Depth-3 Identity Testing, Sparse Factorization and Duality

TLDR
This work studies the complexity of two special but natural cases of identity testing—first is a case of depth-3 PIT, the other ofdepth-4 PIT; generalize this technique by combining it with a generalized Chinese remaindering to solve these two problems (over any field).

The simple, little and slow things count: on parameterized counting complexity

TLDR
This contribution is intended to be a self-contained and minimally technical exposition of the material in this thesis, which investigates the complexity of combinatorial counting problems in the frameworks of parameterized (and exponential-time) complexity.

Sparse instances of hard problems

TLDR
Under the hypothesis that coNP is not in NP/poly, the results imply surprisingly tight lower bounds for parameters of interest in several areas, namely sparsification, kernelization in parameterized complexity, lossy compression, and probabilistically checkable proofs.
