On the eigenfunctions of the complex Ornstein-Uhlenbeck operators
eigenfunctions complex Ornstein-Uhlenbeck operators
2016/1/20
Starting from the 1-dimensional complex-valued Ornstein-Uhlenbeck process, we present two natural ways to imply the associated eigenfunctions of the 2-dimensional normal Ornstein-Uhlenbeck operators i...
Noncommutative Pieri Operators on Posets
Noncommutative algebra symmetric function matrix coefficient hopf hopf algebra algebraic function
2014/12/29
We consider graded representations of the algebra NC of noncommutative symmetric functions on the Z-linear span of a graded poset P. The matrix coefficients of such a representation give a Hopf morphi...

Grid polyhedron the singular lattice polyhedron
2014/12/25
Let P be a simple lattice polytope. We define an action of the Hecke operators on E(P), the Ehrhart polynomial of P, and describe their effect on the coefficients of E(P). We also describe how the Bri...
Let F be a real quadratic field with ring of integers O and with class number 1. Let Γ be a congruence subgroup of GL2 (O)GL2() . We describe a technique to compute the action of the Hecke operators o...

Stein operators are differential operators which arise within the so-called Stein's method for stochastic approximation. We propose a new mechanism for constructing such operators for arbitrary (conti...
Additive inverse regression models with convolution-type operators
Inverse regression Additive models Convolution-type operators Mathematical subject codes: primary 62G08 secondary 62G15 62G20
2013/4/27
In a recent paper Birke and Bissantz (2008) considered the problem of nonparametric estimation in inverse regression models with convolution-type operators. For multivariate predictors nonparametric m...
The aim of this paper is to examine the notion of
random operators from a Fr&het space into a Banach one. Characteristic
function, convergence and decomposabitity of random operators
are studied.

We prove some results concerning the almost sure
approximation 01 contractions in L, by projections, unitary operators
or partial isometries. In particular, a unitary operator for which no
subseque...

For the absolutely @-summing operators T: X + Y
between Banach spaces X and Y we consider martingale inequalities of
the type

We show that for a von Neumann algebra in standard
form with cyclic and separating tracial vector, and some classes of
noncommutative processes on it, stopping and integrals of these processes
