Doob meyer decomposition proof

WebMeyer's decomposition can be obtained by passage to the limit from the discrete case. Our proof clarifies the relation between Doob decom position and Meyer's decomposition. The natural process will appear as the continuous analogue of the process occurring in the Doob de composition in the discrete case. It will be noticed that our proof that WebDec 26, 2014 · CHAPTER 3. The Doob-Meyer decomposition theorem. by Jan van Neerven.
