Lie discrete symmetries of lattice equations
We extend two of the methods previously introduced to find discrete symmetries of differential equations to the case of difference and differentialdifference equations. As an example of the application of the methods, we construct the discrete symmetries of the discrete Painlevé I equation and of the Toda lattice equation.
متن کاملArbitrary lattice symmetries via block copolymer nanomeshes
Self-assembly of block copolymers is a powerful motif for spontaneously forming well-defined nanostructures over macroscopic areas. Yet, the inherent energy minimization criteria of self-assembly give rise to a limited library of structures; diblock copolymers naturally form spheres on a cubic lattice, hexagonally packed cylinders and alternating lamellae. Here, we demonstrate multicomponent na...
متن کاملSymmetries of the k - bounded partition lattice
We generalize the symmetry on Young’s lattice, found by Suter, to a symmetry on the k-bounded partition lattice of Lapointe, Lascoux and Morse. Résumé. Nous généralisons la symmetrie sur le treillis de Young, découvert par Suter, à une symétrie sur le treillis des partages bornés par k et étudié par Lapointe, Lascoux and Morse.
متن کاملLattice Regularization of the Chiral Schwinger Model
We analyze the chiral Schwinger model on an infinite lattice using the continuum definition of the fermion determinant and a linear interpolation of the lattice gauge fields. For non-compact and Wilson formulation of the gauge field action it is proven that the effective lattice model is Osterwalder-Schrader positive, which is a sufficient condition for the reconstruction of a physical Hilbert ...
متن کاملChiral Pertubation Theory with Lattice Regularization
We study the structure and perform some explicit calculations for the power ultraviolet divergences and their renormalization in the Chiral Pertubation Theory with lattice regularization in 1 and 2 loops.
