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
