He also worked with hypergeometric differential equations in 1857 using complex analytical methods and presented the solutions through the behavior of closed paths about singularities (described by the monodromy matrix ). Source: Internet
The proof of the existence of such differential equations by previously known monodromy matrices is one of the Hilbert problems. Source: Internet
