Supercritical Schrödinger equations involving integro-differential operators and vanishing potentials
Ronaldo C. Duarte, Diego Ferraz
This paper is devoted to the study of the existence of positive and bounded solutions for a Schrödinger type equation defined on the entire Euclidean space, involving a general int…
Concentration-compactness via profile decomposition for systems of coupled Schrödinger equations of Hamiltonian type
Anderson Cardoso, João Marcos do Ó, Diego Ferraz
We analyse Hamiltonian-type systems of second-order elliptic PDE invariant under a non-compact group and, consequently, involve a lack of compactness of the Sobolev embedding. We s…
Existence of bound states for quasilinear elliptic problems involving critical growth and frequency
Diego Ferraz
In this paper we study the existence of bound states of the following class of quasilinear problems, \begin{equation*} \left\{ \begin{aligned} &-\varepsilon ^pΔ_pu+V(x)u^{p-1}=f(u)…
New Results on Edge-coloring and Total-coloring of Split Graphs
Fernanda Couto, Diego Amaro Ferraz, Sulamita Klein
A split graph is a graph whose vertex set can be partitioned into a clique and an independent set. A connected graph is said to be -admissible if admits a special spanning t…
Simpler and efficient characterizations of tree t-spanners for graphs with few P4's and (k, l)-graphs
Fernanda Couto, Luís Cunha, Diego Ferraz
A tree -spanner of a graph is a spanning tree in which the distance between any two adjacent vertices of is at most . The smallest for which has a tree $t…
Concentration-compactness at the mountain pass level for nonlocal Schrödinger equations
João Marcos do Ó, Diego Ferraz
The aim of this paper is to study a concentration-compactness principle for inhomogeneous fractional Sobolev space for As an application we esta…
Concentration-compactness principle for nonlocal scalar field equations with critical growth
João Marcos do Ó, Diego Ferraz
The aim of this paper is to study a concentration-compactness principle for homogeneous fractional Sobolev space for As an a…
