Marginality and convexity in partition function form games
(Springer Nature, 2021-08)
In this paper an order on the set of embedded coalitions is studied in detail. This allows us to define new notions of superaddivity and convexity of games in partition function form which are compared to other proposals ...

The berth allocation and quay crane assignment problem with crane travel and setup times
(Elsevier, 2024-02)
In this paper, we propose a new approach for including quay crane travel and setup times in the berth allocation and quay crane assignment problem. We first develop a new mixed integer linear programming model (MILP) for ...

Properties of Poincaré half-maps for planar linear systems and some direct applications to periodic orbits of piecewise systems
(University of Szeged, 2023)
This paper deals with fundamental properties of Poincaré half-maps defined on a straight line for planar linear systems. Concretely, we focus on the analyticity of the Poincaré half-maps, their series expansions (Taylor ...

Semigroups of composition operators on Hardy spaces of Dirichlet series
(Elsevier, 2023)
We consider continuous semigroups of analytic functions {Φt}t≥0 in the so-called Gordon-Hedenmalm class G, that is, the family of analytic functions Φ:C+→C+ giving rise to bounded composition operators in the Hardy space ...

Maximum Box Problem on Stochastic Points
(Springer, 2021-10)
Given a finite set of weighted points in Rd (where there can be negative weights), the maximum box problem asks for an axis-aligned rectangle (i.e., box) such that the sum of the weights of the points that it contains is ...

Uniform upper bound for the number of limit cycles of planar piecewise linear differential systems with two zones separated by a straight line
(Elsevier, 2023-03)
The existence of a uniform upper bound for the maximum number of limit cycles of planar piecewise linear differential systems with two zones separated by a straight line has been subject of interest of hundreds of papers. ...

A Succinct Characterization of Period Annuli in Planar Piecewise Linear Differential Systems with a Straight Line of Nonsmoothness
(Springer, 2023-07)
We close the problem of the existence of crossing period annuli in planar piecewise linear differential systems with a straight line of nonsmoothness. In fact, a characterization for the existence of such objects is provided ...

Structural Formulas for Matrix-Valued Orthogonal Polynomials Related to 2×2 Hypergeometric Operators
(Springer, 2022-03)
We give some structural formulas for the family of matrix-valued orthogonal polynomials of size 2×2 introduced by C. Calderón et al. in an earlier work, which are common eigenfunctions of a differential operator of ...
