Positive solutions of the p-Laplacian involving a superlinear nonlinearity with zeros
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
Using a combination of several methods, such as variational methods. the sub and supersolutions method, comparison principles and a priori estimates. we study existence, multiplicity, and the behavior with respect to lambda ...
Defeito zero para bilhares convexos em H2
(Universidade Federal de Minas GeraisBrasilPrograma de Pós-Graduação em MatemáticaUFMG, 2017-12-14)
Let Q be a strictly geodesically convex region in the hyperbolic plane bounded
by a closed curve with strictly positive geodesic curvature. A billiard on Q
consists in the particle’s free motion suffering elastic collisions ...

Attenuation of diffracted multiples with an apex-shifted tangent-squared radon transform in image space
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2006)
In this paper, we propose a method to attenuate diffracted multiples with an apex-shifted tangent-squared Radon transform in angle domain common image gathers (ADCIG) . Usually, where diffracted multiples are a problem, ...
