tuned conjunction tactics: slightly smaller proof terms;
nipkow [Sun, 17 Jun 2007 18:47:03 +0200] rev 23413
tuned laws for cancellation in divisions for fields.
chaieb [Sun, 17 Jun 2007 13:39:50 +0200] rev 23412
moved nonzero_mult_divide_cancel_right to Ring_and_Field as nonzero_mult_divide_cancel_right'; tuned proofs
chaieb [Sun, 17 Jun 2007 13:39:48 +0200] rev 23411
Added eta_conv and eta-expansion conversion: waiting for it to be in thm.ML; exported is_refl
chaieb [Sun, 17 Jun 2007 13:39:45 +0200] rev 23410
gen_qelim_conv now reduces the universal quatifier to the existential one; Now also deals with Ex f for eta-contracted f;
chaieb [Sun, 17 Jun 2007 13:39:39 +0200] rev 23409
thin_prems_tac first max-scopes universal quantifiers; eta_conv moved to Pure/conv.ML

Tuned error messages; tuned;
chaieb [Sun, 17 Jun 2007 13:39:32 +0200] rev 23407
normalizer conversions depend on the proof context; added functions for conversion and wrapper that sill depend on the variable ordering (_ord)
chaieb [Sun, 17 Jun 2007 13:39:29 +0200] rev 23406
added theorems nonzero_mult_divide_cancel_right' nonzero_mult_divide_cancel_left' ordered_field_no_lb ordered_field_no_ub
