The work by Ioannis Karatzas and Steven E. Shreve is considered a foundational text in continuous-time stochastic processes. First published in 1988 as part of the Graduate Texts in Mathematics series by Springer Nature , it provides a rigorous measure-theoretic treatment of the subject. Core Objectives and Approach

: Detailed construction and analysis of sample paths, including properties like nowhere differentiability and quadratic variation.

: Establishing the necessary filtrations and properties for continuous-time processes.
