Edge separators for quasi-binary trees
Jorge Ramirez Alfonsin, Serge Tishchenko
One wishes to remove edges of a vertex-weighted tree such that the weights of the induced connected components are approximately the same. How well can one do it ? In…
On the number of numerical semigroups of prime power genus
Shalom Eliahou, Jorge Ramirez Alfonsin
Given , the number of numerical semigroups of genus equal to is the subject of challenging conjectures of Bras-Amorós. In this…
On the Frobenius Number of Fibonacci Numerical Semigroups
J. M. Marin, J. Ramirez Alfonsin, M. P. Revuelta
In this paper we compute the Frobenius number of certain {\em Fibonacci numerical semigroups}, that is, numerical semigroups generated by a set of Fibonacci numbers, in terms of Fi…
On tiling rectangles via the Frobenius number
J. Ramirez Alfonsin
In this paper, we give some sufficient conditions for a -dimensional rectangle to be tiled with a set of bricks. These conditions are obtained by using the so-called Frobenius n…
