Symmetries of supersymmetric integrable hierarchies of KP type
This article is devoted to the systematic study of additional (non-isospectral) symmetries of constrained (reduced) supersymmetric integrable hierarchies of KP type—the so-called SKP(R;MB,MF) models.Expand

Virasoro symmetry of constrained KP hierarchies
Abstract The conventional formulation of additional nonisospectral sysmmetries for the full Kadomtsev-Petviashvili (KP) integrable hierarchy is not compatible with the reduction to the importantExpand

Supersymmetric Kadomtsev-Petviashvili hierarchy: ''Ghost'' symmetry structure, reductions, and Darboux-Backlund solutions
This paper studies Manin–Radul supersymmetric Kadomtsev–Petviashvili hierarchy (MR-SKP) in three related aspects: (i) We find an infinite set of additional (“ghost”) symmetry flows spanning the sameExpand

Stable Emergent Universe -- A Creation without Big-Bang
Based on an earlier introduced new class of generalized gravity-matter models defined in terms of two independent non-Riemannian volume forms (alternative generally covariant integration measureExpand

Unified dark energy and dust dark matter dual to quadratic purely kinetic K-essence
We consider a modified gravity plus single scalar-field model, where the scalar Lagrangian couples symmetrically both to the standard Riemannian volume-form (spacetime integration measure density)Expand

Emergent cosmology, inflation and dark energy
A new class of gravity–matter models defined in terms of two independent non-Riemannian volume forms (alternative generally covariant integration measure densities) on the space–time manifold areExpand

Bäcklund and Darboux Transformations. The Geometry of Solitons
We show that any multi-component matrix KP hierarchy is equivalent to the standard onecomponent (scalar) KP hierarchy endowed with a special infinite set of abelian additional symmetries, generatedExpand

Method of Squared Eigenfunction Potentials in Integrable Hierarchies of KP Type
Abstract:The method of squared eigenfunction potentials (SEP) is developed systematically to describe and gain new information about the Kadomtsev–Petviashvili (KP) hierarchy and its reductions.Expand

Construction of KP hierarchies in terms of finite number of fields and their abelianization
Abstract The 2M-boson representations of the KP hierarchy are constructed in terms of M mutually independent two-boson KP representations for arbitrary number M. Our construction establishes theExpand

Strings, p-Branes and Dp-Branes With Dynamical Tension
We discuss a new class of brane models (extending both p-brane and Dp-brane cases) where the brane tension appears as an additional dynamical degree of freedom instead of being put in by hand as anExpand
