Integrable lattices and their sub-lattices: from the discrete Moutard (discrete Cauchy-Riemann) 4-point equation to the self-adjoint 5-point scheme

A. Doliwa, P. Grinevich, M. Nieszporski +1

We introduce the sub-lattice approach, a procedure to generate, from a given integrable lattice, a sub-lattice which inherits its integrability features. We consider, as illustrati…

Flag Spaces in KP Theory and Virasoro Action on \det D_j and Segal-Wilson τ-Function

P. G. Grinevich, A. Yu. Orlov

It is well-known that the algebra of vector fields on the circle acts on the space of Riemann surfaces with a marked point and a local parameter at this point. We show that this ac…
