Singular Solutions to Monge-Ampère Equation

open access: yesAnalysis in Theory and Applications, 2022
We construct merely Lipschitz and $C^{1,α}$ with rational $α ∈ (0, 1 − 2/n]$ viscosity solutions to the Monge-Ampère equation with constant right hand side.

Brane-Universe in Six Dimensions [PDF]

open access: yes, 2001
Growing non-singular solution of 6-dimensional Einstein equations for the 4-brane in infinite transversal 2-space is found. This solution provides gravitational trapping of matter and 4-dimensional gravity on the brane without extra delta-like source ...

Black-hole solution without curvature singularity and closed timelike curves

open access: yes, 2014
With a prescribed Coulomb-type energy-momentum tensor, an exact solution of the Einstein field equations over a nonsimply-connected manifold is presented. This spherically symmetric solution has neither curvature singularities nor closed timelike curves.

Exact monopole instantons and cosmological solutions in string theory from abelian dimensional reduction [PDF]

open access: yes, 1996
We compute the exact string vacuum backgrounds corresponding to the non-compact coset theory $SU(2,1)/SU(2)$. The conformal field theory defined by the level $k= 4$ results in a five dimensional singular solution that factorizes in an asymptotic region ...

Space-time domain solutions of the wave equation by a non-singular boundary integral method and Fourier transform

open access: yes, 2017
The general space-time evolution of the scattering of an incident acoustic plane wave pulse by an arbitrary configuration of targets is treated by employing a recently developed non-singular boundary integral method to solve the Helmholtz equation in the
