Concentration with a single sign-changing layer at the higher critical exponents
(Walter de Gruyter GMBH, 2018)
We exhibit a new concentration phenomenon for the supercritical problem -Delta v = lambda v + vertical bar v vertical bar(p-2) v in Omega, v = 0 on partial derivative Omega, as p -> 2*(N,m) from below, where 2*(N, m) := 2 ...
Ray tracing em tempo real usando hierarchical scene signed distance fields
(Universidade Federal de Santa MariaBrasilCiência da ComputaçãoUFSMPrograma de Pós-Graduação em Ciência da ComputaçãoCentro de Tecnologia, 2019-03-25)
Ray tracing is an important technique for obtaining photo-realistic images. The basic algorithm
is well known and consists of tracing rays from a synthetic camera position by
calculating the color of objects colliding ...
On Dirichlet problems with singular nonlinearity of indefinite sign
(2015)
Let Ω be a smooth bounded domain in RN , N ≥ 1, let K, M be two nonnegative functions and let α, γ > 0. We study existence and nonexistence of positive solutions for singular problems of the form −Δu = K(x)u−α − λM (x)u−γ ...
Sign-changing blowing-up solutions for thecritical nonlinear heat equation
(Scuola Normale Superiore, 2020)
Let Omega be a smooth bounded domain in R-n and denote the regular part of the Green function on Omega with Dirichlet boundary condition by H(x, y). Assume the integer k0 is sufficiently large, q is an element of Omega and ...
