Harmonic maps and soliton theory
نویسنده
چکیده
The study of harmonic maps of a Riemann sphere into a Lie group or, more generally, a symmetric space has been the focus for intense research by a number of Differential Geometers and Theoretical Physicists. As a result, these maps are now quite well understood and are seen to correspond to holomorphic maps into some (perhaps infinite-dimensional) complex manifold. For more information on this circle of ideas, the Reader is referred to the articles of Guest and Valli in these proceedings.

Harmonic tori in spheres and complex projective spaces
Introduction A map : M ! N of Riemannian manifolds is harmonic if it extremises the energy functional: Z jdj 2 dvol on every compact subdomain of M. Harmonic maps arise in many diierent contexts in Geometry and Physics (for an overview, see 15,16]) but the setting of concern to us is the following: take M to be 2-dimensional and N to be a Riemannian symmetric space of compact type. In this case...
متن کاملHarmonic Tori and Their Spectral Data
One of the earliest applications of modern integrable systems theory (or “soliton theory”) to differential geometry was the solution of the problem of finding all constant mean curvature (CMC) tori in R3 (and therefore, by taking the Gauss map, finding all non-conformal harmonic maps from a torus to S2). At its simplest level this proceeds from the recognition that the Gauss-Codazzi equations o...
متن کاملHarmonic maps, Bäcklund-Darboux transformations and ”line soliton” analogs
Harmonic maps from R2 or one-connected domain Ø ⊂ R2 into GL(m, C) and U(m) are treated. The GBDT version of the BäcklundDarboux transformation is applied to the case of the harmonic maps. A new general formula on the GBDT transformations of the Sym-Tafel immersions is derived. A class of the harmonic maps similar in certain ways to line-solitons is obtained explicitly and studied.

متن کاملLoop Group Decompositions in Almost Split Real Forms and Applications to Soliton Theory and Geometry
We prove a global Birkhoff decomposition for almost split real forms of loop groups, when an underlying finite dimensional Lie group is compact. Among applications, this shows that the dressing action by the whole subgroup of loops which extend holomorphically to the exterior disc on the U -hierarchy of the ZS-AKNS systems, on curved flats and on various other integrable systems, is global for ...
متن کاملSoliton-induced nonlocal resonances observed through high-intensity tunable spectrally compressed second-harmonic peaks
Experimental data of femtosecond thick-crystal second-harmonic generation show that when tuning away from phase matching, a dominating narrow spectral peak appears in the second harmonic that can be tuned over hundreds of nanometers by changing the phase-mismatch parameter. Traditional theory explains this as phase matching between a sideband in the broadband pump to its second harmonic. Howeve...
