Global Analytic Solutions for the Nonlinear Schr\"odinger Equation
We prove the existence of global analytic solutions to the nonlinear
Schr\"odinger equation in one dimension for a certain type of analytic initial
data in .Comment: Corrected errors in proofs in section
Regularization of Discontinuous Foliations: Blowing up and Sliding Conditions via Fenichel Theory
We study the regularization of an oriented 1-foliation on where is a smooth manifold and is a
closed subset, which can be interpreted as the discontinuity locus of
. In the spirit of Filippov's work, we define a sliding and sewing
dynamics on the discontinuity locus as some sort of limit of the
dynamics of a nearby smooth 1-foliation and obtain conditions to identify
whether a point belongs to the sliding or sewing regions.Comment: 32 page
A Remark on Unconditional Uniqueness in the Chern-Simons-Higgs Model
The solution of the Chern-Simons-Higgs model in Lorenz gauge with data for
the potential in and for the Higgs field in is
shown to be unique in the natural space for , where corresponds to finite energy. Huh and Oh
recently proved local well-posedness for , but uniqueness was obtained
only in a proper subspace of Bourgain type. We prove that any solution in
must in fact belong to the space
, hence it is the unique solution obtained by Huh and Oh
Incorporating waiting time in competitive location models: Formulations and heuristics
In this paper we propose a metaheuristic to solve a new version of the Maximum Capture Problem. In the original MCP, market capture is obtained by lower traveling distances or lower traveling time, in this new version not only the traveling time but also the waiting time will affect the market share. This problem is hard to solve using standard optimization techniques. Metaheuristics are shown to offer accurate results within acceptable computing times.Market capture, queuing, ant colony optimization
