Boolean Functions and Permanents of Sylvester Hadamard Matrices
Mathematics, 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 ...

The Dittert's function on a set of nonnegative matrices
International 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.

Approximating the Permanent [PDF]
SIAM Journal on Computing, 1989 A randomised approximation scheme for the permanent of a 0–1s presented. The task of estimating a permanent is reduced to that of almost uniformly generating perfect matchings in a graph; the latter is accomplished by simulating a Markov chain whose states are the matchings in the graph.

Journal of the American Philosophical Association, 2021 AbstractTemporal nihilism is the view that our lives will not matter after we die. According to the standard interpretation, this is because our lives will not make a permanent difference. Many who consider the view thus reject it by denying that our lives need to have an eternal impact.

Per-Spectral Characterizations Of Some Bipartite Graphs
Discussiones Mathematicae Graph Theory, 2017 A graph is said to be characterized by its permanental spectrum if there is no other non-isomorphic graph with the same permanental spectrum. In this paper, we investigate when a complete bipartite graph Kp,p with some edges deleted is determined by its ...

Medical Education Online, 2016 The training of physicians in the past century was based primarily on responsibility and the chain-of-command. Those with the bulk of that responsibility in the fields of pediatrics and internal medicine were residents. Residents trained the medical students and supervised them carefully in caring for patients.
