Condorcet domains of tiling type
Vladimir I. Danilov, Alexander V. Karzanov, Gleb A. Koshevoy
A Condorcet domain (CD) is a collection of linear orders on a set of candidates satisfying the following property: for any choice of preferences of voters from this collection, a s…
The strong thirteen spheres problem
Oleg Musin, Alexey Tarasov
The thirteen spheres problem is asking if 13 equal size nonoverlapping spheres in three dimensions can touch another sphere of the same size. This problem was the subject of the fa…
Trace inequalities for products of matrices
Shigeru Furuichi, Ken Kuriyama, Kenjiro Yanagi
In this short paper, we study some trace inequalities of the products of the matrices and the power of matrices by the use of elementary calculations.
Characterizations of generalized entropy functions by functional equations
Shigeru Furuichi
We shall show that a two-parameter extended entropy function is characterized by a functional equation. As a corollary of this result, we obtain that the Tsallis entropy function i…
On refined Young inequalities and reverse inequalities
Shigeru Furuichi
In this paper, we show refined Young inequalities for two positive operators. Our results refine the ordering relations among the arithmetic mean, the geometric mean and the harmon…
On Min-Cost Multiflow Problem in Node-Capacitated Undirected Networks
Maxim A. Babenko, Alexander V. Karzanov
We consider an undirected graph with a set of terminals, and with nonnegative integer capacities and costs of nodes . A path…
