Gaussian binomials and the number of sublattices
Yi Ming Zou
The purpose of this short communication is to make some observations on the connections between various existing formulas of counting the number of sublattices of a fixed index in…
Indices of Coincidence Isometries of the Hyper Cubic Lattice
Yi Ming Zou
The problem of computing the index of a coincidence isometry of the hyper cubic lattice is considered. The normal form of a rational orthogonal matrix is analyzed…
Structures of Coincidence Symmetry Groups
Yi Ming Zou
The structure of the coincidence symmetry group of an arbitrary -dimensional lattice in the -dimensional Euclidean space is considered by describing a set of generators. Part…
Invariants and orthogonal -polynomials associated with
Yi Ming Zou
The spaces of invariants and the zonal spherical functions associated with quantum super 2-shpheres defined by are discussed. Connection between the zonal s…
Quantum super spheres and their transformation groups, representations, and little -Jacobi polynomials
Yi Ming Zou
Quantum super 2-shpheres and the corresponding quantum super transformation group are introduced in analogy to the well-known quantum 2-shpheres and quantum SL(2), connection betwe…
Spherical functions on homogeneous superspaces
Ruibin Zhang, Yi Ming Zou
Homogeneous superspaces arising from the general linear supergroup are studied within a Hopf algebraic framework. Spherical functions on homogeneous superspaces are introduced, and…
