Deformations and Geometric Cosets *
I review some marginal deformations of SU(2) and SL(2, R) Wess–Zumino–Witten models , which are relevant for the investigation of the moduli space of NS5/F1 brane configurations. Particular emphasis is given to the asymmetric deformations, triggered by electric or magnetic fluxes. These exhibit critical values, where the target spaces become exact geometric cosets such as S 2 ≡ SU(2)/U(1) or Ad...
متن کاملIntegrable Systems and Isomonodromy Deformations
We analyze in detail three classes of isomondromy deformation problems associated with integrable systems. The first two are related to the scaling invariance of the n× n AKNS hierarchies and the Gel’fand-Dikii hierarchies. The third arises in string theory as the representation of the Heisenberg group by [(L)+, L] = I where L is an nth order scalar differential operator. The monodromy data is ...
متن کاملIntegrable deformations of a polygon
The new integrable mapping with a simple geometric interpretation is presented. This mapping arise from the nonlinear superposition principle for the Bäcklund transformations of some vector evolution equation. 1 Recuttings of the polygon Let us consider a set of points vj ∈ R , j ∈ ZN , N ≥ 3 and define the transformation Rk as reflection of the point vk about the normal hyperplane passing thro...
متن کاملIntegrable Deformations of Selfdual Gravity
A group of volume-preserving diffeomorphisms in 3D turns out to play a key role in an Einstein-Maxwell theory whose Weyl tensor is selfdual and whose Maxwell tensor has algebraically general anti-selfdual part. This model was first introduced by Flaherty and recently studied by Park as an integrable deformation of selfdual gravity. A twisted volume form on the corresponding twistor space is sho...
متن کاملReciprocal Transformations and Deformations of Integrable Hierarchies
j=s aiD i x and [K]i = ai, and ǫ is an arbitrary constant. The compatibility conditions for (2) and (3) read Ltq = [P≥1(L ) + ǫ[L]0Dx, L], q = 1, 2, . . . . (4) Note that the hierarchy (4) with ǫ = 0 was discovered by Kupershmidt [2]. The goal of the present work is to show that, under a suitable change of dependent and independent variables x, ti, and uk, the “deformed” hierarchy (4) can be tr...
