On the existence of solution of a two‐point boundary value problem in a cylindrical floating zone
Existence of one solution for a two‐point boundary value problem with a positive parameter Q arising in the study of surface‐tension‐induced flows of a liquid metal or semiconductor is studied. On the basis of the upper‐lower solution method and Schauder′s fixed point theorem, it is proved that the problem admits a solution when 0 ≤ Q ≤ 12.683.

Multi-term fractional differential equations with nonlocal boundary conditions
We introduce and study a new kind of nonlocal boundary value problems of multi-term fractional differential equations. The existence and uniqueness results for the given problem are obtained by applying standard fixed point theorems.

Generalized Green′s functions for higher order boundary value matrix differential systems
In this paper, a Green′s matrix function for higher order two point boundary value differential matrix problems is constructed. By using the concept of rectangular co‐solution of certain algebraic matrix equation associated to the problem, an existence condition as well as an explicit closed form expression for the solution of possibly not well‐posed ...

Tensor Complementarity Problem and Semi-positive Tensors
The tensor complementarity problem $(\q, \mathcal{A})$ is to $$\mbox{ find } \x \in \mathbb{R}^n\mbox{ such that }\x \geq \0, \q + \mathcal{A}\x^{m-1} \geq \0, \mbox{ and }\x^\top (\q + \mathcal{A}\x^{m-1}) = 0.$$ We prove that a real tensor $\mathcal ...

Generalized two point boundary value problems. existence and uniqueness
An algorithm is presented for finding the pseudo‐inverse of a rectangular matrix. Using this algorithm as a tool, existence and uniqueness of solutions to two point boundary value problems associated with general first order matrix differential equations are established.
