In this work, we propose goodness-of-fit tests based on the Kullback-Leibler information for the Birnbaum-Saunders model, in which we initially considered uncensored data and, in a second moment, we considered data with ...

In this work we study the existence, uniqueness and exact controllability at the boundary and internal to the linear wave equation with Dirichlet boundary condition. In addition, we did a study of the existence, uniqueness ...

In this work we use variational methods to show the existence of weak solutions for two types problems. The first of them is a nonlinear problem of the form 8<:− u + u = k hu + g(x, u), R Nu 2 H1(RN) where N 3. The ...

In this work we study the existence of nodal solution for some Elliptic problems in bounded and unbounded domains. We deal with cases subcritical, critical, exponential critical and exponential subcritical growth. The main ...

In this work we present a characterization of varieties of associative algebras with exponent less than or equal to two, overelds of characteristic zero. Werst show a result dueto Kemer which states that a variety has ...

In this work we study the spaces Lp(x)() and W1, p(x)(), as well as existence of weak solutions for elliptic problems of type 8<:− p(x)u = f(x, u), x 2, u 2 W1, p(x)(), where RN is a bounded domain or = RN; p(x) > 1 ...

In this work we study some properties of abstract differential equations in Banach spaces and we apply the results for study the non local evolution equation of neural fields @u(x; t) @t = 􀀀�u(x; t) + J (f u)(x; t) ...

In this work, using sub and supersolutions and variational methods on Orlicz-Sobolev spaces, we study the existence of multiple positive solutions for a class of quasilinear elliptic problems.
