The Geometry of the Super KP Flows
نویسنده
چکیده
A supersymmetric generalization of the Krichever map is used to construct algebro-geometric solutions to the various super KadomtsevPetviashvili (SKP) hierarchies. The geometric data required consist of a suitable algebraic supercurve of genus g (generally no t a super Riemann surface) with a distinguished point and local coordinates (z, 0) there, and a generic line bundle of degree g 1 with a local trivialization near the point. The resulting solutions to the Manin-Radul SKP system describe coupled deformations of the line bundle and the supercurve itself, in contrast to the ordinary KP system which deforms line bundles but not curves. Two new SKP systems are introduced: an integrable "Jacobian" system whose solutions describe genuine Jacobian flows, deforming the bundle but not the curve; and a nonintegrable "maximal" system describing independent deformations of bundle and curve. The Kac-van de Leur SKP system describes the" same deformations as the maximal system, but in a different parametrization.

The Super W ∞ Symmetry of the Manin - Radul Super KP Hierarchy
We show that the Manin-Radul super KP hierarchy is invariant under super W ∞ transformations. These transformations are characterized by time dependent flows which commute with the usual flows generated by the conserved quantities of the super KP hierarchy.
متن کاملA Nonstandard Supersymmetric Kp Hierarchy
We show that the supersymmetric nonlinear Schrödinger equation can be written as a constrained super KP flow in a nonstandard representation of the Lax equation. We construct the conserved charges and show that this system reduces to the super mKdV equation with appropriate identifications. We construct various flows generated by the general nonstandard super Lax equation and show that they con...

A two dimensional numerical model of shallow water equations was developed tocalculate sub and super-critical open channel flows. Utilizing an implicit scheme the steady stateequations were discretized based on control volume method. Collocated grid arrangement was appliedwith a SIMPLEC like algorithm for depth-velocity coupling. Power law scheme was used fordiscretization of convection and dif...

Analyzing the geometry of Iranian Islamic gardens based on the Quran’s characteristics of paradise
Iranian Islamic gardens like almost every cultures, represent beauty and happiness and improve the public perception. It has also special geometry with philosophical concept related to Islam’s doctrine that is the focus of this research. Following Quran’s contents, paradise is a beautiful sophisticated garden that something flows under its trees. So the comparison between the somatic geometry o...
