The following work constitutes the third and final part of the original planned three- volume treatment of ‘Stochastic Analysis’. The first one appeared in 1995, as the second edition of an earlier publication (the 1979 version), and the second part, termed ‘Inference Theory’ (of stochastic processes) appeared in 2010 (as a revised, and enlarged work of the original 2000 year publication). These two volumes are pub- lished originally by Netherlands’ publishers. That publication house was acquired by Springer and then reissued under their own name (2nd edition of 2nd volume). The current volume completes the originally planned coverage of the trilogy. Many new developments are covered in these volumes. I shall now indicate the contents of this volume for a brief view of the included topics presented in six chapters. Each chapter also has its contents outlined in an early paragraph.
