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 continuous and continuous_on to the HOL image; isCont is an abbreviation for continuous (at x) (isCont is now restricted to a T2 space)
2013-01-17 hoelzl 2013-01-17 generalize compact_path_image to topological_space
2013-01-14 hoelzl 2013-01-14 differentiate (cover) compactness and sequential compactness
2012-12-14 hoelzl 2012-12-14 Remove the indexed basis from the definition of euclidean spaces and only use the set of Basis vectors

2010-09-13 nipkow 2010-09-13 renamed lemmas: ext_iff -> fun_eq_iff, set_ext_iff -> set_eq_iff, set_ext -> set_eqI
2010-07-01 huffman 2010-07-01 convert theorem path_connected_sphere to euclidean_space class
2010-06-21 hoelzl 2010-06-21 Introduce a type class for euclidean spaces, port most lemmas from real^'n to this type class.
