2004-07-01 paulson 2004-07-01 new treatment of binary numerals
2004-06-24 paulson 2004-06-24 replaced monomorphic abs definitions by abs_if
2004-05-01 wenzelm 2004-05-01 tuned instance statements;
2004-03-08 paulson 2004-03-08 generic theorems about exponentials; general tidying up
2004-03-04 paulson 2004-03-04 new material from Avigad, and simplified treatment of division by 0
2004-03-01 paulson 2004-03-01 new Ring_and_Field hierarchy, eliminating redundant axioms
2004-02-15 paulson 2004-02-15 Polymorphic treatment of binary arithmetic using axclasses
2004-02-05 paulson 2004-02-05 tidying up, especially the Complex numbers
2004-02-03 paulson 2004-02-03 further tidying of the complex numbers
2004-02-03 paulson 2004-02-03 tidying of the complex numbers
2004-01-13 paulson 2004-01-13 types complex and hcomplex are now instances of class ringpower: omitting redundant lemmas
2004-01-12 paulson 2004-01-12 Added lemmas to Ring_and_Field with slightly modified simplification rules Deleted some little-used integer theorems, replacing them by the generic ones in Ring_and_Field Consolidated integer powers
2004-01-09 paulson 2004-01-09 Defining the type class "ringpower" and deleting superseded theorems for types nat, int, real, hypreal
2004-01-06 paulson 2004-01-06 Ring_and_Field now requires axiom add_left_imp_eq for semirings. This allows more theorems to be proved for semirings, but requires a redundant axiom to be proved for rings, etc.
2004-01-01 paulson 2004-01-01 conversion of Real/PReal to Isar script; type "complex" is now in class "field"
2004-01-01 paulson 2004-01-01 tweaking of lemmas in RealDef, RealOrd
2003-12-23 paulson 2003-12-23 converting Complex/Complex.ML to Isar
2003-05-05 paulson 2003-05-05 new session Complex for the complex numbers
