چکیده
The lattice Gelfand-Dickey hierarchy is a version of the hierarchy. A special case KdV Inspired by recent work Buryak and Rossi, we propose an extension extended system has infinite number logarithmic flows alongside usual flows. We present Lax, Sato Hirota equations factorization problem difference operators that captures whole set solutions. construction this resembles 1D bigraded Toda hierarchy, but exhibits several novel features as well.

Extended Named Entity Hierarchy
The tagging of Named Entities (NE), the names of particular things or classes and numeric expressions, is regarded as an important component technology for many NLP applications. These applications include Information Extraction, from which it was born, QuestionAnswering, Summarization and Information Retrieval. However, up to now, the number of NE types has been quite limited, 7 in MUC, 8 in I...
متن کاملAn extended Harry Dym hierarchy
Abstract An extended Harry Dym hierarchy is constructed by using eigenfunctions and adjoint eigenfunctions of the spectral problems of the Harry Dym hierarchy associated with the pseudo-differential operator L = u∂ +u0 +u1∂−1 + · · ·. The corresponding Lax presentation possesses a self-consistent source involving squared eigenfunctions. The resulting extended Harry Dym hierarchy is reduced to t...
متن کاملToda Lattice Hierarchy and Zamolodchikov’s Conjecture
where the domain of integration for the operator is (0,∞). The quantity e(p) does not depend on tn’s. It should be remarked that our tn corresponds to tn/2 of refs.[1, 2]. Independently, Bernard and LeClair showed that φ(t) solves the shG equation[3]. Quite recently, Tracy and Widom proved that above φ(t) satisfies both the mKdV hierarchy and the shG hierarchy[2]. Their proof is based on the fa...
متن کاملRenormalization of the lattice Boltzmann hierarchy.
Is it possible to solve Boltzmann-type kinetic equations using only a small number of particle velocities? We introduce a technique of solving kinetic equations with a (arbitrarily) large number of particle velocities using only a lattice Boltzmann method on standard, low-symmetry lattices. The renormalized kinetic equation is validated with an exact solution of the planar Couette flow at moder...
متن کاملToda Lattice Hierarchy and Generalized String Equations
String equations of the p-th generalized Kontsevich model and the compactified c = 1 string theory are re-examined in the language of the Toda lattice hierarchy. As opposed to a hypothesis postulated in the literature, the generalized Kontsevich model at p = −1 does not coincide with the c = 1 string theory at self-dual radius. A broader family of solutions of the Toda lattice hierarchy includi...
