[isabelle] Quantifying over locales
I'm trying to see how one could quantify over locales. For example, if I have:
locale T =
fixes f :: "nat => nat"
and c :: nat
assumes ax: "f c = 1"
and if I want to prove that there exists a locale taking 2 parameters
such that applying the first parameter to the second is equal to 0
lemma "EX P. P (f::real=>real) (c::real) --> f c > 0"
but that would be a trivial lemma since P f c can simply be False. So
how should one properly formulate the lemma? Is there a way of doing
so without specifying on the type that each parameter should take?
Thanks in advance.
