Problems of stress singularities in single or multi-material corners have been addressed by many authors over the years. Most presented closed-form corner-eigenequations for special cases, and often there is no easy way to check if solution correct. In this work, we present a general computational tool that can solve different cases singularity problems under generalized plane strain. The semi-...

— This paper present a synthesis concerning applications of Gaussian coherent states in semi-classical analysis for Schrödinger type equations, time dependent or time independent. We have tried to be self-contained and elementary as far as possible. In the first half of the paper we present the basic properties of the coherent states and explain in details the construction of asymptotic solutio...

Recent focus on the importance of cold, unshocked gas accretion in galaxy formation – not explicitly included in semi-analytic studies – motivates the following detailed comparison between two inherently different modelling techniques: direct hydrodynamical simulation and semi-analytic modelling. By analysing the physical assumptions built into the GASOLINE simulation, formulae for the emergent...

Finite temperature Euclidean SU(2) lattice gauge fields generated in the confinement phase close to the deconfinement phase transition are subjected to cooling. The aim is to identify long-living, almost-classical local excitations which carry (generically non-integer) topological charge. Two kinds of spatial boundary conditions (fixed holonomy and standard periodic boundary conditions) are app...

In this talk, we recall the most important features of the Dilatonic Black Holes which arise in the framework of the Einstein-Dilaton-Gauss-Bonnet theory and which are dressed with a classical long range dilaton field in contradiction with the existing " no-hair " theorems of the Theory of General Relativity. We demonstrate linear stability of these black hole solutions under small spacetime-de...

Using the semi-classical method of Nikishov-Ritus (NR), the derivation of the transition rate of the beamsstrahlung process is reviewed. This method uses the Furry Picture and the exact solutions of the Dirac equation in the external field potential. For future linear colliders, the nominal machine parameters are such that this external field can be considered to be a constant crossed electroma...

The convergence of the iterative solutions of the transport equations of cosmic muon and tau neutrinos propagating through Earth is studied and analyzed. For achieving a fast convergence of the iterative solutions of the coupled transport equations of ντ , ν̄τ and the associated τ ± fluxes, a new semi–analytic input algorithm is presented where the peculiar τ–decay contributions are implemented ...
