A decay estimate for the Fourier transform of certain singular measures in $R^{4}$ and applications

Tomás Godoy, Pablo Rocha

We consider, for a class of functions $φ : R^{2} ∖ {0} \to R^{2}$ satisfying a nonisotropic homogeneity condition, the Fourier transform $μ^$ …

Lp-Lq estimates of some convolution operators with singular measures on the Heisenberg group

Pablo Rocha, Tomas Godoy

We study the boundedness from Lp(Hn) into Lq(Hn) of certain convolution operators with singular measures on the Heisenberg group.

On Dirichlet problems with singular nonlinearity of indefinite sign

Tomás Godoy, Uriel Kaufmann

Let $Ω$ be a smooth bounded domain in $R^{N}$ , $N \geq 1$ , let $K$ , $M$ be two nonnegative functions and let $α, γ > 0$ . We study existence and nonexistence of positive solutio…

Existence of strictly positive solutions for sublinear elliptic problems in bounded domains

Tomas Godoy, Uriel Kaufmann

Let $Ω$ be a smooth bounded domain in $R^{N}$ and let $m$ be a possibly discontinuous and unbounded function that changes sign in $Ω$ . Let $f:\left[ 0,\infty\right) \right…
