Hello,
how can i apply the following lemma only once?
lemma "a = a + 1" (the soundness of the lemma is here irrelevant)
I mean i only want to rewrite the "a" with "a+1" only once..cause by default it will rewrite forever and i dont want that.
Thank you!

Hi Roger,

try the 'subst' method:
apply (subst your_theorem)
