Boundary data smoothness for solutions of nonlocal boundary value problems.
… under certain conditions partial derivatives and differences exist, with respect to boundary conditions, for solutions of nonlocal boundary value problems and solve the variational equation in the derivative case and a specific linear difference equation in the difference case. Lastly, we provide …

Difference equations with semisimple Galois groups in positive characteristic
… F be a field with an automorphism sigma on F. A (linear) difference equation over F is an equation of the form sigma(y)=Ay with A in GL_n(F) and y a vector consisting of n indeterminates. There is the notion of a Picard-Vessiot ring which is in some sense a "smallest" difference ring extension R …

Stability Analysis of Systems of Difference Equations
Difference equations are the discrete analogs to differential equations. While the independent variable of differential equations normally is a continuous time variable, t, that of a difference equation is a discrete time variable, n, which measures time in intervals. A feature of difference …
