Solutions of fractional nabla difference equations - existence and uniqueness [PDF]
Opuscula Mathematica, 2016 In this article, we discuss existence, uniqueness and dependency of solutions of nonlinear fractional nabla difference equations in a Banach space equipped with a suitable norm, using the contractive mapping approach. As an application of the established

Fractional SDEs with stochastic forcing: Existence, uniqueness, and approximation
Nonlinear Analysis, 2023 In this article, we are interested in fractional stochastic differential equations (FSDEs) with stochastic forcing, i.e., to FSDE we add a stochastic forcing term.

A uniqueness result for the continuity equation in two dimensions [PDF]
, 2014 We characterize the autonomous, divergence-free vector fields $b$ on the plane such that the Cauchy problem for the continuity equation $\partial_t u + div(bu) = 0$ admits a unique bounded solution (in the weak sense) for every bounded initial datum; the

Existence of weak solutions for abstract hyperbolic-parabolic equations
International Journal of Mathematics and Mathematical Sciences, 1994 In this paper we study the Existence and Uniqueness of solutions for the following Cauchy problem:A2u″(t)+A1u′(t)+A(t)u(t)+M(u(t))=f(t), t∈(0,T) (1)u(0)=u0; A2u′(0)=A212u1; where A1 and A2 are bounded linear operators in a ...

Existence and uniqueness of optimal matrix scalings [PDF]
[1992] Proceedings of the 31st IEEE Conference on Decision and Control, 1995 The authors consider the optimal diagonal scaling problem for a complex \(n \times n\) matrix \(M\). Using the reformulation as a convex optimization problem, they show that the set of optimal diagonal scalings is nonempty and bounded if and only if \(M\) is irreducible.

LARGE SOLUTIONS FOR YAMABE AND SIMILAR PROBLEMS ON DOMAINS IN RIEMANNIAN MANIFOLDS [PDF]
, 2011 We present a unified approach to study large positive solutions (i.e., u(x) -> infinity as x -> partial derivative Omega) of the equation Delta u + hu - k psi(u) = -f in an arbitrary domain Omega.

Qualitative aspects of the quasistationary electromagnetic field [PDF]
Journal of Electrical and Electronics Engineering, 2009 The paper proposes some properties of theelectromagnetic field magnitudes so that theuniqueness and existence theorems may beformulated. The field equations are written asdistribution. The constitutive relation may be nonlinear.

Existence and uniqueness of Bowen–York trumpets [PDF]
Classical and Quantum Gravity, 2011 We prove the existence of initial data sets which possess an asymptotically flat and an asymptotically cylindrical end. Such geometries are known as trumpets in the community of numerical relativists.

Codes and designs—existence and uniqueness
Discrete Mathematics, 1991 This is a well written general survey concerning the usefulness of coding theory in proving existence and uniqueness results in design theory. The scope of the paper is limited, dealing significantly with only two examples. The coding theory aspects of the work of C. Lam, et. al. on the non-existence of a projective plane of order 10 is outlined.
