In this section, difference equation (or recurrence) means constant coefficient homogeneous linear difference equation (CCHLDE). We will show how to solve all such difference equations. That is, for ...

Differential Galois theory provides an algebraic framework for understanding the symmetries and solvability of linear differential equations by associating to each equation a group of ...

Difference equations arise in both the modeling of discrete dynamical systems and in various purely mathematical contexts, including the numerical integration of differential equations. This chapter ...
