2013-09-27 Andreas Lochbihler 2013-09-27 add relator for 'a filter and parametricity theorems
2013-09-24 huffman 2013-09-24 factor out new lemma
2013-09-24 huffman 2013-09-24 replace lemma with more general simp rule
2013-09-03 wenzelm 2013-09-03 tuned proofs -- less guessing;
2013-09-03 wenzelm 2013-09-03 tuned proofs -- clarified flow of facts wrt. calculation;
2013-08-27 hoelzl 2013-08-27 renamed typeclass dense_linorder to unbounded_dense_linorder
2013-07-25 haftmann 2013-07-25 factored syntactic type classes for bot and top (by Alessandro Coglio)
2013-05-30 wenzelm 2013-05-30 tuned headers;
2013-04-25 hoelzl 2013-04-25 revert #916271d52466; add non-topological linear_continuum type class; show linear_continuum_topology is a perfect_space
2013-04-25 hoelzl 2013-04-25 renamed linear_continuum_topology to connected_linorder_topology (and mention in NEWS)
2013-04-24 hoelzl 2013-04-24 spell conditional_ly_-complete lattices correct
2013-04-09 hoelzl 2013-04-09 remove the within-filter, replace "at" by "at _ within UNIV" (This allows to remove a couple of redundant lemmas)
2013-03-26 hoelzl 2013-03-26 separate SupInf into Conditional_Complete_Lattice, move instantiation of real to RealDef
2013-03-22 hoelzl 2013-03-22 move continuous_on_inv to HOL image (simplifies isCont_inverse_function)
2013-03-22 hoelzl 2013-03-22 move connected to HOL image; used to show intermediate value theorem
2013-03-22 hoelzl 2013-03-22 move compact to the HOL image; prove compactness of real closed intervals; show that continuous functions attain supremum and infimum on compact sets
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)
2013-03-22 hoelzl 2013-03-22 generalize Bfun and Bseq to metric spaces; Bseq is an abbreviation for Bfun
2013-03-22 hoelzl 2013-03-22 move first_countable_topology to the HOL image
2013-03-22 hoelzl 2013-03-22 move topological_space to its own theory
