This is done by constructing a local geometric realization of quantum field theories together with a local application of mirror symmetry, This construction is not based on any duality conjecture and thus reduces non-trivial quantum field theory results to much better understood T-dualities of type II strings. Moreover it can be used in principle to construct in a systematic way the vacuum structure for arbitrary N = 2 gauge theories with matter representations.en-USJournal Article2019-09-2210.1016/S0550-3213(97)00282-4
