The classical differential Galois theory studies symmetry groups of solutions of linear differential equations. We will discuss a parameterized differential Galois theory, which studies symmetry groups of the solutions of linear differential equations having coefficients that depend on parameters. The Galois groups that arise are differential algebraic groups, which are defined by differential (possibly, non-linear) equations in the parameters.
