Supercharacters, symmetric functions in noncommuting variables, and related Hopf algebras
noncommuting variables related Hopf algebras
2015/8/14
We identify two seemingly disparate structures: supercharacters, a useful way of doing
Fourier analysis on the group of unipotent uppertriangular matrices with coefficients in a finite
field, and th...
We show that elements of a natural basis of the Iwahori xed vectors in a principal series representation of a reductive p-adic group
satisfy certain recursive relations. The precise identities invol...
The bounded spherical functions for the free two step nilpotent Lie group
nilpotent Lie group representation theory spherical function
2011/1/19
In this paper, we give the expressions for the bounded spherical functions, or equivalently the spherical functions of positive type, for the free two-step nilpotent Lie groups endowed with the action...
Projective completions of affine varieties via degree-like functions
Projective completions of affine varieties degree-like functions
2011/1/18
We introduce and study a class of projective completions of ane algebraic varieties which generalize the construction of toric varieties from convex rational polytopes.
Strongly Regular Graphs Constructed from $p$-ary Bent Functions
Strongly Regular Graphs Constructed math
2010/11/23
In this paper, we generalize the construction of strongly regular graphs in [Y. Tan et al., Strongly regular graphs associated with ternary bent functions, J. Combin.Theory Ser. A (2010), 117, 668-68...
On the canonical structure of regular pencil of singular matrix-functions
singular matrix-functions math
2010/11/15
The work is devoted to investigation of the canonical structure of regular, in domain of definition ${\cal U}\subseteq {\mathbb R}^{m}$, the pencil of matrix-functions $A(x)+\lambda B(x)$. It is supp...
Using Hook Schur Functions to Compute Matrix Cocharacters
Using Hook Schur Functions Compute Matrix Cocharacters
2010/11/12
We use hook Schur functions to compute trace cocharacters of matrices in hooks. As an example we compute the cocharacters of 3 x 3 matrices in the one by two hook
Ratio Vectors of Polynomial-Like Functions
Polynomial Real roots Ratio vector Critical points
2010/1/22
Let be a hyperbolic polynomial-like function of the form where are given positive real numbers and . Let be the critical points of lying in . Define the ratios We prove that . These boun...
HILBERT SPACE OF PROBABILITY DENSITY FUNCTIONS BASED ON AITCHISON GEOMETRY
Bayes' theorem Fourier coefficients Haar basis Aitchison distance Simplex Least squares approximation
2007/12/12
The set of probability functions is a convex subset of $L^1$ and it does not have a linear space structure when using ordinary sum and multiplication by real constants. Moreover, difficulties arise wh...
Extension and Separation of Vector Valued Functions
Vector Valued Functions paracompact Hausdorff space
2010/3/5
It is proved that: If X is a paracompact Hausdorff space and E is a Frechet lattice then (X, E) has the separation property. This is employed to extend some varies of functions that are known for spac...
