Uniqueness implies existence for (n,p) boundary value problems [PDF]

open access: yes, 2010
The uniqueness of solutions of certain boundary value problems implies their existence for the nth order nonlinear ordinary differential equation y(n)=f(x,y,y',y'',....,y(n-1)) This existence is established by using shooting methods and yields results ...

Existence and uniqueness of solution for multidimensional parabolic partial differential‐algebraic equations arising in semiconductor modeling [PDF]

open access: yes, 2021
This paper concerns with a compact network model combined with distributed models for semiconductor devices. For linear RLC networks containing distributed semiconductor devices, we construct a mathematical model that joins the differential-algebraic ...

Existence and uniqueness of optimal matrix scalings [PDF]

open access: yes[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.

A uniqueness result for the continuity equation in two dimensions [PDF]

open access: yes, 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

LARGE SOLUTIONS FOR YAMABE AND SIMILAR PROBLEMS ON DOMAINS IN RIEMANNIAN MANIFOLDS [PDF]

open access: yes, 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.
