Existence of two solutions for singular Φ-Laplacian problems

2022

AbstractExistence of two solutions to a parametric singular quasi-linear elliptic problem is proved. The equation is driven by theΦ\Phi-Laplacian operator, and the reaction term can be nonmonotone. The main tools employed are the local minimum theorem and the Mountain pass theorem, together with the truncation technique. GlobalC1,τ{C}^{1,\tau }regularity of solutions is also investigated, chiefly viaa prioriestimates and perturbation techniques.

Multiple point spaces of finite holomorphic maps

2016

Esta tesis trata sobre espacios múltiples de aplicaciones holomorfas finitas entre variedades complejas. Nuestro enfoque es el de la teoría de singularidades, y las aplicaciones serán consideradas bajo la relación de A-equivalencia, es decir, salvo cambios de coordenadas en partida y llegada. Nos centramos en relacionar propiedades de los espacios de puntos múltiples con propiedades como la A-estabilidad y la A-determinación finita. En generaEl trabajo está organizado de la siguiente manera: El Capítulo 1 contiene los fundamentos básicos necesarios para el resto del trabajo. En el Capítulo 2 definimos los espacios de puntos múltiples de una aplicación. Demostramos que solo hay una manera de…

Minori migranti soli o non accompagnati e le nuove forme di affiancamento a tutori legali

2019

Nell’ambito del sistema di accoglienza in Italia, sappiamo che sono molteplici gli interventi mirati al riconoscimento del bisogno educativo che i migranti manifestano. Nello specifico del contributo, che prende avvio da una ricognizione empirica e problematica sul fenomeno migratorio, si intende riflettere sulla particolare situazione in cui si vengono a trovare i minori migranti soli o non accompagnati, i quali, oltre a dover ri-definire la propria identità tra il passato e le aspettative future, si trovano a sperimentare l’esperienza migratoria da soli, ovvero privi di assistenza e di rappresentanza da parte dei genitori o di altri adulti per loro legalmente responsabili. Si tratta, dunq…

ETAT TOPOLOGIQUE DE L'ESPACE TEMPS A L'ECHELLE 0

2002

We propose in this research a new solution regarding the existence and the content of the initial spacetime singularity. In the context of topological field theory we consider that the initial singularity of space-time corresponds to a zero size singular gravitational instanton characterized by a Riemannian metric configuration (++++) in dimension D = 4. Connected with some unexpected topological data corresponding to the zero scale of space-time, the initial singularity is thus not considered in terms of divergences of physical fields but can be resolved in the frame of topological field theory. We get this result from the physical observation that the pre-spacetime is in a thermal equilib…

Numerical Recovery of Source Singularities via the Radiative Transfer Equation with Partial Data

2013

The inverse source problem for the radiative transfer equation is considered, with partial data. Here we demonstrate numerical computation of the normal operator $X_{V}^{*}X_{V}$ where $X_{V}$ is the partial data solution operator to the radiative transfer equation. The numerical scheme is based in part on a forward solver designed by F. Monard and G. Bal. We will see that one can detect quite well the visible singularities of an internal optical source $f$ for generic anisotropic $k$ and $\sigma$, with or without noise added to the accessible data $X_{V}f$. In particular, we use a truncated Neumann series to estimate $X_{V}$ and $X_{V}^{*}$, which provides a good approximation of $X_{V}^{*…
