Part of our approach allows a semi-infinite cohomology interpretation, and the latter can be used to define sheaves of chiral differential operators on some homogeneous spaces
For example, modular invariance for vertex operator superalgebras requires inclusion of supercharacters of (untwisted) modules, and more importantly, the characters of σ
Hence the corresponding integrable equations may be considered as an intermediate case between generalized Thirring and (non-Abelian) Toda equation. 4.3.1 Case of second
Group classification of the three-dimensional equations describing flows of fluids with internal inertia, where the potential function W = W (ρ, ρ), is presented1. The given ˙
The differential operator defined in this article plays a key rˆole in conformal differential geometry in dimension 4 and is now known as the Paneitz operator.. Key words:
The purpose of this paper is to reduce the equations of dispersive flows ( 1 ) and ( 2 ) to complex valued equations by constructing a good moving
The nine-dimensional bound is sharp: normal forms for the contact-equivalence classes of these maximally symmetric generic hyperbolic equations are derived and explicit
In fact, our aim is, on the one hand, to present new Miura transformations between the ABS equations and Volterra-type difference equations and on the other hand, to show that the
