On the type of Wiener-Hopf C*-algebras
(American Mathematical Society, 1990-08-02) -
Isomorphism of the Toeplitz C*-algebras for the Hardy and Bergman spaces on certain Reinhardt domains
(American Mathematical Society, 1992-09-01) -
Symplectic leaves and deformation quantization
(American Mathematical Society, 1996-01-01)In this paper, we show that for any classical simple compact Poisson Lie group K, there is no quantization of K using the quantum group Kq, which is both group-preserving and symplectic leaf-preserving. -
The structure of quantum spheres

A note on the cone restriction conjecture in the cylindrically symmetric case
(American Mathematical Society, 2009-08-28)In this paper, we present two arguments showing that the classical linear adjoint cone restriction conjecture holds for the class of functions supported on the cone and invariant under spatial rotation in all dimensions. ... -
Maximizers for the Strichartz and the Sobolev-Strichartz inequalities for the Schrödinger equation
(Texas State University, Department of Mathematics, 2009-09-04)In this paper, we first show that there exists a maximizer for the non-endpoint Strichartz inequalities for the Schr¨odinger equation in all dimensions based on the recent linear profile decomposition result. We then present ... -
A space of small spread without the usual properties

p-points in iterated forcing extensions
(American Mathematical Society, 1978-05-03)Selective ultrafilters exist in direct iterated ccc extensions whose length has uncountable cofinality, as do p-points which are not selective. Nonselective p-points also exist e.g. in an iterated Laver or Mathias extension ... -
A reformulation of S and L
(American Mathematical Society, 1978-05-02)We give a combinatorial statement which is equivalent to the existence of an S space, and one equivalent to the existence of an L space, thus verifying the widespread intuition that the problem of S and L is essentially ... -
More paracompact box products
(American Mathematical Society, 1979-04-02)We show that if there is no family of cardinality less than c which dominates ww, then the box product of countably many compact first-countable spaces is paracompact; hence the countable box product of compact metrizable ... -
Easy S and L groups
(American Mathematical Society, 1979-04-03)We give a simple proof that the existence of strong S or L spaces implies the existence of strong S or L groups; in fact the algebraic structure can be varied quite a bit. We also construct, under CH, S and L groups whose ... -
Height and width of superatomic Boolean algebras
(American Mathematical Society, 1985-05-02) -
CH and Ostaszewski spaces
(American Mathematical Society, 1999-03-08)There are models of CH without Ostaszeswki spaces. If X is locally compact and sub-Ostaszewski, there is a forcing PX which does not add reals and which forces ``X is not sub-Ostaszewski''. -
Revising the NCTM Standards

Adaptive Boundary and Point Control of Linear Stochastic Distributed Parameter Systems
(Society for Industrial and Applied Mathematics, 1994-05-05)An adaptive control problem for the boundary or the point control of a linear stochastic distributed parameter system is formulated and solved in this paper. The distributed parameter system is modeled by an evolution ... -
Ergodic Boundary/Point Control of Stochastic Semilinear Systems
(Society for Industrial and Applied Mathematics, 1998-03-05)A controlled Markov process in a Hilbert space and an ergodic cost functional are given for a control problem that is solved where the process is a solution of a parameter-dependent semilinear stochastic differential ... -
Discretized Maximum Likelihood and Almost Optimal Adaptive Control of Ergodic Markov Models
(Society for Industrial and Applied Mathematics, 1998-04-02)Three distinct controlled ergodic Markov models are considered here. The models are a discrete time controlled Markov process with complete observations, a controlled diffusion process with complete observations, and a ... -
A singular stochastic integral equation
(American Mathematical Society, 1982-03-05)This note is devoted to the discussion of the stochastic differential equation $ XdX + YdY = 0$, $ X$ and $ Y$ being continuous local martingales. A method to construct solutions of this equation is given. -
On the Quadratic Variation of Two-Parameter Continuous Martingales
(Institute of Mathematical Statistics (IMS), 1984-02-02)Let M={M(z),z∈[0,1]2} be a two-parameter square integrable continuous martingale. We prove the sample continuity of the quadratic variation of M using an Ito's differentiation formula for M2. -
A Characterization of the Spatial Poisson Process and Changing Time
(Institute of Mathematical Statistics (IMS), 1986-02-06)Watanabe proved that if Xt is a point process such that Xt−t is a martingale, then Xt is a Poisson process and this result was generalized by Bremaud for doubly stochastic Poisson processes. Here we define two-parameter ...
