Uniqueness and stability of limit cycles in planar piecewise linear differential systems without sliding region
(Elsevier, 2023)
In this paper, we consider the family of planar piecewise linear differential systems with two zones separated by a straight line without sliding regions, that is, differential systems whose flow transversally crosses ...

Banzhaf values for cooperative games with fuzzy characteristic function
(Taylor & Francis, 2021)
The Banzhaf value, which determines the power of each agent in a cooperative game, has been used in the literature to analyze fuzzy cooperative situations. In this paper, we propose two Banzhaf values for games with ...

Second order error bounds for POD-ROM methods based on first order divided differences
(Elsevier, 2023)
This note proves for the heat equation that using BDF2 as time stepping scheme in POD-ROM methods with snapshots based on difference quotients gives both the optimal second order error bound in time and pointwise estimates.

The boundary focus–saddle bifurcation in planar piecewise linear systems. Application to the analysis of memristor oscillators
(Elsevier, 2018-10)
Among the boundary equilibrium bifurcations in planar continuous piecewise linear systems with two zones separated by a straight line, the focus–saddle bifurcation corresponds with a one-parameter transition from a situation ...
