Re: [isabelle] how to use brackets in lemma



Hi 

succeed to add new lines in ubuntu's firefox, i send again the question

failed to parse lemma when prove the following
would like to see any further usage when continuing adding letters into it
lemma mfold5 [simp]:"mfold5 f [a,b,c,d,e] x = f e (f d (f c (f b (f a x))))"
lemma mfold [simp]:"mfold f [a,b,c] x = f c (f b (f a x))"apply(simp_all)apply(auto)donelemma mfoldr [simp]:"mfoldr f [a,b,c] x = f a (f b (f c x))"apply(induct_tac x)apply(auto)donelemma mfoldl [simp]:"mfoldl f x [a,b,c] = f (f (f x a) b) c"apply(induct_tac x)apply(auto)done

Regards,

Martin
