Topological Multivortex Solutions of the Self-Dual Maxwell-Chern-Simons-Higgs System

We study existence and various behaviors of topological multivortices solutions of the relativistic self-dual Maxwell-Chern-Simons-Higgs system. We first prove existence of general topological solutions by applying variational methods to the newly discovered minimizing functional. Then, by an iteration method we prove existence of topological solutions satisfying some extra conditions, which we call admissible solutions. We establish asymptotic exponential decay estimates for these topological solutions. We also investigate the limiting behaviors of the admissible solutions as parameters in our system goes to some limits. For the Abelian Higgs limit we obtain strong convergence result, while for the Chern-Simons limit we only obtained that our admissible solutions are weakly approximating one of the Chern-Simons solutions.Comment: 29 pages, Tmain.tex is bod

Rural children’s work and school education in the context of rapid economic growth in South Korea

This paper explores how children’s work, in its broadest sense, and the related values and attitudes concerning childhood, have evolved in the context of rapid economic growth in South Korea. It discusses how ideas about children’s main activities, and their status and relationships within the family, have changed and how children’s roles and responsibilities are seen by members of different generations. It interrogates the changing ideas of work in contemporary children’s lives and presents data from a relatively under-researched part of the world
