Complex transitions between spiking, bursting and silent regimes in a new memristive Rulkov neuronal model

Miguel Moreno, Alexandre R. Nieto, Miguel A. F. Sanjuán

The Rulkov model, which simulates the behavior of biological neurons, is modified by replacing one of its control parameters with a memristive, sigmoid-type function of finite memo…

Vibrational resonance in a frequency-adaptive learning Duffing system

Zhongqiu Wan, Jianhua Yang, Feng Tian +2

Vibrational resonance focuses on the resonance behavior of a nonlinear system when it is subjected to both a weak low-frequency characteristic signal and a high-frequency auxiliary…

Consistency of Bayes factors for linear models

Elías Moreno, J. J. Serrano-Pérez, F. Torres-Ruiz

The quality of a Bayes factor crucially depends on the number of regressors, the sample size and the prior on the regression parameters, and hence it has to be established in a cas…

Brackets in multicontact geometry and multisymplectization

Manuel de León, Rubén Izquierdo-López, Xavier Rivas

In this paper we introduce a graded bracket of forms on multicontact manifolds. This bracket satisfies a graded Jacobi identity as well as two different versions of the Leibniz rul…

Practical Introduction to Action-Dependent Field Theories

Manuel de León, Jordi Gaset Rifà, Miguel C. Muñoz-Lecanda +2

Action-dependent field theories are systems where the Lagrangian or Hamiltonian depends on new variables that encode the action. They model a larger class of field theories, includ…

The -adic Jaynes-Cummings model in symplectic geometry

Luis Crespo, Álvaro Pelayo

The notion of classical -adic integrable system on a -adic symplectic manifold was proposed by Voevodsky, Warren and the second author a decade ago in analogy with the real c…

Ewald's Conjecture and integer points in algebraic and symplectic toric geometry

Luis Crespo, Álvaro Pelayo, Francisco Santos

We solve several open problems concerning integer points of polytopes arising in symplectic and algebraic geometry. In this direction we give the first proof of a broad case of Ewa…

A new perspective on nonholonomic brackets and Hamilton-Jacobi theory

Manuel de León, Manuel Lainz, Asier López-Gordón +1

The nonholonomic dynamics can be described by the so-called nonholonomic bracket on the constrained submanifold, which is a non-integrable modification of the Poisson bracket of th…

Evidence for a radiation belt around a brown dwarf

J. B. Climent, J. C. Guirado, M. Pérez-Torres +2

Radio observations of ultracool dwarfs, objects comprising brown dwarfs and the very lowest mass stars, have mainly focused on analyzing their light-curve and spectral energy distr…

Hamilton-Jacobi theory for nonholonomic and forced hybrid mechanical systems

Leonardo Colombo, Manuel de León, María Emma Eyrea Irazú +1

A hybrid system is a system whose dynamics is given by a mixture of both continuous and discrete transitions. In particular, these systems can be utilised to describe the dynamics…

Hamilton-Jacobi theory and integrability for autonomous and non-autonomous contact systems

Manuel de León, Manuel Lainz, Asier López-Gordón +1

In this paper, we study the integrability of contact Hamiltonian systems, both time-dependent and independent. In order to do so, we construct a Hamilton--Jacobi theory for these s…
