The Dittert's function on a set of nonnegative matrices

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
Let Kn denote the set of all n×n nonnegative matrices with entry sum n. For X∈Kn with row sum vector (r1,…,rn), column sum vector (c1,…,cn), Let ϕ(X)=∏iri+∏jcj−perX. Dittert's conjecture asserts that ϕ(X)≤2−n!/nn for all X∈Kn with equality iff X=[1/n]n×n.

Boolean Functions and Permanents of Sylvester Hadamard Matrices

open access: yesMathematics, 2021
One of the fastest known general techniques for computing permanents is Ryser’s formula. On this note, we show that this formula over Sylvester Hadamard matrices of order 2m, Hm, can be carried out by enumerating m-variable Boolean functions with an ...
