FunctionalAnalysisAnalysisMeasureTheory Similar to standard Lebesgue integration theory (as well as integration of Progressive Processes), we begin by defining the integral for simple Banach Space Valued Functions: and subsequently for arbitrary Bochner Measurable functions via approximation by simple functions , s.t. : Indeed, we have the following necessary and sufficient conditions for a Bochner Measurable function to be Bochner Integrable:

  1. for all

Examples:

  1. The Sobolev Space
