This thesis lies in the field of automated deduction, i.e. the development of algorithms aiming at proving automatically some mathematical conjectures. In this thesis, the conjectures that we want to prove belong to an extension of propositional logic called ``formula schemas''. Those objects allow to represent infinitely many propositional formulae in a finite way (similarly to the way that regular languages finitely represent infinitely many words). Proving a formula schema amounts to prove (at once) all the formulae that it represents. We show that the problem of proving formula schemas is undecidable in general. The remaining part of the thesis presents algorithms that still try to prove schemas (event though, of course, they do not ter...
