Summing Logarithmic Expansions for Elliptic
Elliptic problems in a two-dimensional domain containing one or several small holes are studied asymptotically in the limit of small hole radius ". As a result of the perturbation , the asymptotic solution to this class of problems contains an innnite logarithmic expansion in powers of ?1= log ". A hybrid asymptotic-numerical technique is used to sum these innnite logarithmic expansions and to ...

متن کاملLogarithmic perturbation theory for radial Klein-Gordon equation with screened Coulomb potentials via h̄ expansions
The explicit semiclassical treatment of logarithmic perturbation theory for the bound-state problem within the framework of the radial Klein-Gordon equation with attractive real-analytic screened Coulomb potentials, contained time-component of a Lorentz four-vector and a Lorentz-scalar term, is developed. Based upon h̄-expansions and suitable quantization conditions a new procedure for deriving ...
متن کاملLogarithmic Terms in Trace Expansions of Atiyah-patodi-singer Problems
Introduction. Let D be a first-order differential operator of Dirac-type from C(X,E1) to C (X,E2) (E1 and E2 Hermitian N -dimensional vector bundles over a compact n-dimensional C ∞ manifold X with boundary ∂X = X ), and let D≥ be the L2-realization defined by the boundary condition Π≥(u|X′) = 0; here Π≥ is the orthogonal projection onto the nonnegative eigenspace for a certain selfadjoint oper...
متن کاملThe Semimartingale Property via Bounded Logarithmic Utility
This paper provides a new condition ensuring the preservation of semimartingality under enlargement of filtrations in the setting of continuous stochastic processes. Our main tool is the concept of utility maximization from mathematical finance. Normally, this approach would require an integration theory for non-semimartingales, however, by applying an approximation procedure we show how this o...
