2014-06-02 hoelzl 2014-06-02 remove superfluous assumption
2014-05-07 hoelzl 2014-05-07 avoid the Complex constructor, use the more natural Re/Im view; moved csqrt to Complex.
2014-04-11 nipkow 2014-04-11 made mult_nonneg_nonneg a simp rule
2014-04-03 hoelzl 2014-04-03 merged DERIV_intros, has_derivative_intros into derivative_intros
2014-04-02 hoelzl 2014-04-02 extend continuous_intros; remove continuous_on_intros and isCont_intros
2014-03-07 paulson 2014-03-07 a few new lemmas
2013-11-12 hoelzl 2013-11-12 add finite_select_induct; move generic lemmas from MV_Analysis/Linear_Algebra to the HOL image
2013-09-12 huffman 2013-09-12 prefer attribute 'unfolded thm' to 'simplified'
2013-08-18 wenzelm 2013-08-18 more symbols;
2013-08-13 wenzelm 2013-08-13 standardized symbols via "isabelle update_sub_sup", excluding src/Pure and src/Tools/WWW_Find;
2013-03-22 hoelzl 2013-03-22 modernized definition of root: use the_inv, handle positive and negative case uniformly, and 0-th root is constant 0
2013-03-22 hoelzl 2013-03-22 move continuous and continuous_on to the HOL image; isCont is an abbreviation for continuous (at x) (isCont is now restricted to a T2 space)
2012-10-19 webertj 2012-10-19 Renamed {left,right}_distrib to distrib_{right,left}.
