摘要:
We give sufficient conditions for a differential equation to have a given semisimple group as its Galois group. For any group G with G(0) = G(1) - - - - - G(r), where each G(i) is a simple group of type A(l), C-l, D-l, E-6, or E-7, we construct a differential equation over C(x) having Galois group G.
