2010-12-29 wenzelm 2010-12-29 explicit file specifications -- avoid secondary load path;
2010-12-08 hoelzl 2010-12-08 cleanup bijectivity btw. product spaces and pairs
2010-12-01 hoelzl 2010-12-01 Generalized simple_functionD and less_SUP_iff. Moved theorems to appropriate places.
2010-12-01 hoelzl 2010-12-01 Replace algebra_eqI by algebra.equality; Move sets_sigma_subset to Sigma_Algebra;
2010-12-01 hoelzl 2010-12-01 Support product spaces on sigma finite measures. Introduce the almost everywhere quantifier. Introduce 'morphism' theorems for most constants. Prove uniqueness of measures on cut stable generators. Prove uniqueness of the Radon-Nikodym derivative. Removed misleading suffix from borel_space and lebesgue_space. Use product spaces to introduce Fubini on the Lebesgue integral. Combine Euclidean_Lebesgue and Lebesgue_Measure. Generalize theorems about mutual information and entropy to arbitrary probability spaces. Remove simproc mult_log as it does not work with interpretations. Introduce completion of measure spaces. Change type of sigma. Introduce dynkin systems.

2010-08-27 hoelzl 2010-08-27 Introduced sigma algebra generated by function preimages.
2010-08-23 hoelzl 2010-08-23 Rewrite the Probability theory. Introduced pinfreal as real numbers with infinity. Use pinfreal as value for measures. Introduces Lebesgue Measure based on the integral in Multivariate Analysis. Proved Radon Nikodym for arbitrary sigma finite measure spaces.
