= Processing of 'Measures, Integrals and Martingales' =

$\S 2$

This book I deem useful to develop (mostly) the theory of the function spaces which are paramount examples in Conway's book on functional analysis.

Nice side effect is that measure theory gains another authoritative source.

Errata and solutions to the exercises are available at http://www.motapa.de/measures_integrals_and_martingales/index.html.

Skipped thus far (that is, what needs to be done still)

 * Structuring of the definitions colliding with Category:Probability Theory (so far, only $\S 4$)
 * Maybe some more Problems
 * Most of the proofs

Other things

 * Category:Sigma-Algebras to be created; maybe also Category:Monotone Classes, Category:Dynkin Systems
 * Go through the exercises again at the end to post up more, and provide better linking
 * Category:Stieltjes Functions, Category:Simple Functions, Category:Dirac Measures, Category:Lebesgue Measure, maybe Category:Discrete Measures
