A nodal inverse problem for a quasi-linear ordinary differential equation in the half-line
(Academic Press Inc Elsevier Science, 2016-07)
In this paper we study an inverse problem for a quasi-linear ordinary differential equation with a monotonic weight in the half-line. First, we find the asymptotic behavior of the singular eigenvalues, and we obtain a ...
Energy dependent potential problems for the one dimensional p-Laplacian operator
(Pergamon-Elsevier Science Ltd, 2019-02)
In this work we analyze a nonlinear eigenvalue problem for the p-Laplacian operator with zero Dirichlet boundary conditions. We assume that the problem has a potential which depends on the eigenvalue parameter, and we show ...
Modification of inertial oscillations by the mesoscale eddy field
The modification of near?surface near?inertial oscillations (NIOs) by the geostrophic vorticity is studied globally from an observational standpoint. Surface drifter are used to estimate NIO characteristics. Despite its ...
Problemas nodales inversos para ecuaciones ordinarias de segundo ordenInverse nodal problems for second order differential equations
(2016-09-14)
En esta tesis centramos nuestra atención en la ecuación de Sturm-Liouville de segundo orden -u''= λρ(x)u, x ∈ (0,1), con cierta condición de borde homogénea. Estudiamos la densidad asintótica de los ceros de las autofunciones ...
The Mittag–Leffler function and its application to the ultra-hyperbolic time-fractional diffusion-wave equation
(Taylor & Francis Ltd, 2016-05)
In this paper we study an n-dimensional generalization of time-fractional diffusion-wave equation, where the Laplacian operator is replaced by the ultra-hyperbolic operator and the time-fractional derivative is taken in ...
