On the Picard principle for ∆ + μ
Given a (local) Kato1 measure μ on Rd \ {0}, d ≥ 2, let H 0 (U) be the convex cone of all continuous real solutions u ≥ 0 to the equation ∆u+ uμ = 0 on the punctured unit ball U satisfying lim|x|→1 u(x) = 0. It is shown that H 0 (U) 6= {0} if and only if the operator f 7→ ∫ U G(·, y)f(y) dμ(y), where G denotes the Green function on U , is bounded on L2(U, μ) and has a norm which is at most one....
متن کاملA generalized form of Ekeland’s variational principle
In this paper we prove a generalized version of the Ekeland variational principle, which is a common generalization of Zhong variational principle and Borwein Preiss Variational principle. Therefore in a particular case, from this variational principle we get a Zhong type variational principle, and a Borwein-Preiss variational principle. As a consequence, we obtain a Caristi type fixed point th...
متن کاملComparison of classical cytogenetics versus interphase FISH in diagnosis of mosaic form of Turner syndrome
Abstract Background: Mosaic form of turner syndrome that represented by two or more cell lines in an affected individual, often has limitation for detection with classical cytogenetic methods. The present study was carried out to compare the efficiency of interphase Fluorescence In Situ Hybridisation (FISH) and cytogenetic techniques in detection of mosaic form of turner syndrome. Method...
متن کاملClassical Lagrangian Model of the Pauli Principle
A classical Lagrangian model of the Pauli potential is introduced. It is shown that the kinematic kinetic energy (1 2 mv 2) in the model approximately reproduces the energy of a free Fermi gas at low temperatures and at densities relevant in nuclear collisions with moderate beam energies. Differences between canonical and kinematic quantities are pointed out. The Pauli potential can be used in ...
متن کاملA Normal Form for Classical Planning Tasks
We describe transition normal form (TNF) for classical planning tasks, where there is a unique goal state and variables occur in an operator precondition iff they appear in the effect. Tasks can be efficiently converted to TNF, all common planning heuristics are invariant under the transformation, and tasks in normal form are easier to study theoretically.
