Embedded, Doubly Periodic Minimal Surfaces
We consider the question of existence of embedded doubly periodic minimal surfaces in R 3 with Scherk–type ends, surfaces that topologically are Scherk’s doubly periodic surface with handles added in various ways. We extend the existence results of H. Karcher and F. Wei to more cases, and we find other cases where existence does not hold.
متن کاملConstruction of doubly-periodic instantons
We construct finite-energy instanton connections over R4 which are periodic in two directions via an analogue of the Nahm transform for certain singular solutions of Hitchin’s equations defined over a 2-torus.
متن کاملDoubly Resonant Optical Periodic Structure
Periodic structures are well known in various branches of physics for their ability to provide a stopband. In this article, using optical periodic structures we showed that, when a second periodicity--very closed to the original periodicity is introduced, large number of states appears in the stopband corresponding to the first periodicity. In the limit where the two periods matches, we have a ...
متن کاملClassification and existence of doubly-periodic instantons
We present a classification of SU(2) instantons on T 2 × R2 according to their asymptotic behaviour. We then study the existence of such instantons for different values of the asymptotic parameters, uncovering some surprising non-existence results. We also describe explicitly the moduli space for unit charge.
متن کاملDoubly Periodic Instantons and Their Constituents
Using the Nahm transform we investigate doubly periodic charge one SU (2) in-stantons with radial symmetry. Two special points where the Nahm zero modes have softer singularities are identified as the locations of instanton core constituents. For a square torus this constituent picture is closely reflected in the action density. In rectangular tori with large aspect ratios the cores merge to fo...
