Uniqueness for elliptic operators on with unbounded coefficients

Forum Mathematicum, 2010
Let A denote a general second order differential operator in divergence form, with real coefficients satisfying only local boundedness conditions. Then, A can be viewed as an unbounded operator Ap on Lp(RN ) with maximal domain D(Ap). The main result of this paper is a criterion for the injectivity of Ap when p ∈ (1,∞).

On quantum stochastic differential equations with unbounded coefficients

Probability Theory and Related Fields, 1990
We prove an existence, uniqueness and unitarity theorem for quantum stochastic differential equations with unbounded coefficients which satisfy an analyticity condition on a common dense invariant domain. This result, applied to the quantum harmonic oscillator, gives a rigorous meaning to a large class of stochastic differential equations that have ...

On Singular Integral Equations with Unbounded Coefficients

2010
Algebras generated by singular integral operators with piecewise continuous coefficients are studied in the papers [1, 2, 3, 4]. The results obtained there allow us to obtain theorems on solvability and index formulas for singular integral operators of new types.

Lyapunov exponents for systems with unbounded coefficients

Dynamical Systems, 2013
In this article we propose a generalization of the concept of Lyapunov exponents for discrete linear systems which may be used in the case of unbounded coefficients. We show some simplest properties of this generalization and apply it to define a generalization of regular system.

Coefficients with unbounded derivatives in hyperbolic equations

Mathematische Nachrichten, 2004
AbstractWe are concerned with the problem of determining the sharp regularity of the coefficients with respect to the time variable t in order to have a well‐posed Cauchy problem in H∞ or in Gevrey classes for linear or quasilinear hyperbolic operators of higher order.

ON ONE ELLIPTIC EQUATION WITH UNBOUNDED COEFFICIENTS

International Conference on Modern Problems of Mathematics, Mechanics and their Applications
Abstract. The paper studies a second-order elliptic equation given on an infinite strip of width 2 and having variable intermediate and junior coefficients. We assume that the intermediate coefficients may not obey the potential. The problem is posed of finding a strong generalized solution of the equation that satisfies periodic conditions at the ...
