Linear-quadratic control for stochastic equations in a Hilbert space with a fractional Brownian motion
(Society for Industrial and Applied Mathematics, 2012-01-01)A linear-quadratic control problem with a finite time horizon for some infinite-dimensional controlled stochastic differential equations driven by a fractional Gaussian noise is formulated and solved. The feedback form of ... -
Adaptive control for semilinear stochastic systems
(Society for Industrial and Applied Mathematics, 2000-01-01)An adaptive, ergodic cost stochastic control problem for a partially known, semilinear, stochastic system in an infinite dimensional space is formulated and solved. The solutions of the Hamilton--Jacobi--Bellman equations ... -
SIGNS IN THE cd-INDEX OF EULERIAN PARTIALLY ORDERED SETS
(American Mathematical Society, 2000-12-28)A graded partially ordered set is Eulerian if every interval has the same number of elements of even rank and of odd rank. Face lattices of convex polytopes are Eulerian. For Eulerian partially ordered sets, the ag vector ... -
Negative Diffusion and Traveling Waves in High Dimensional Lattice Systems
(Society for Industrial and Applied Mathematics, 2013)We consider bistable reaction diffusion systems posed on rectangular lattices in two or more spatial dimensions. The discrete diffusion term is allowed to have positive spatially periodic coefficients, and the two spatially ... -
A Nonoverlapping Domain Decomposition Method for Incompressible Stokes Equations with Continuous Pressures
(Society for Industrial and Applied Mathematics, 2013)A nonoverlapping domain decomposition algorithm is proposed to solve the linear system arising from mixed finite element approximation of incompressible Stokes equations. A continuous finite element space for the pressure ... -
Compact bilinear operators and commutators
(American Mathematical Society, 2013-07-01)A notion of compactness in the bilinear setting is explored. Moreover, commutators of bilinear Calderón-Zygmund operators and multiplication by functions in a certain subspace of the space of functions of bounded mean ... -
Quasi Multiplication and K-groups
(Cambridge University Press, 2013-02-28)We give a negative answer to the question raised by Mart Abel about whether his proposed definition of K0 and K1 groups in terms of quasi multiplication is indeed equivalent to the established ones in algebraic K-theory. -
Absolute continuity and convergence of densities for random vectors on Wiener chaos
(Institute of Mathematical Statistics (IMS), 2013-02-11)The aim of this paper is to establish some new results on the absolute continuity and the convergence in total variation for a sequence of d-dimensional vectors whose components belong to a finite sum of Wiener chaoses. ... -
Central limit theorem for an additive functional of the fractional Brownian motion II

Central limit theorem for a Stratonovich integral with Malliavin calculus
(Institute of Mathematical Statistics, 2013)The purpose of this paper is to establish the convergence in law of the sequence of “midpoint” Riemann sums for a stochastic process of the form f′(W)f′(W), where WW is a Gaussian process whose covariance function satisfies ... -

Optimal Contool for a Mixed Flow of Hamiltonian and Gradient Type in Space of Probability Measures
(American Mathmatical Society, 2013-08)Abstract. In this paper we investigate an optimal control problem in the space of measures on R2. The problem is motivated by a stochastic interacting particle model which gives the 2-D Navier-Stokes equations in their ... -

On the spectra of simplicial rook graphs
(2014-05-05)The \emph{simplicial rook graph} $\SR(d,n)$ is the graph whose vertices are the lattice points in the $n$th dilate of the standard simplex in $\mathbb{R}^d$, with two vertices adjacent if they differ in exactly two ... -
Classification of Ding's Schubert Varieties: Finer Rook Equivalence
(Canadian Mathematical Society, 2007-02)K.~Ding studied a class of Schubert varieties in type A partial flag manifolds, indexed by integer partitions \lambda and in bijection with dominant permutations. He observed that the Schubert cell structure of X_\lambda ... -

Rigidity theory for matroids
(European Mathematical Society, 2007)Combinatorial rigidity theory seeks to describe the rigidity or flexibility of bar-joint frameworks in Rd in terms of the structure of the underlying graph G. The goal of this article is to broaden the foundations of ...
