ABSTRACT

A conditional expectation operator plays an important role in geometry of Banach spaces. However, the main issue is with regards to the existence of a conditional expectation operator that permits other objects to be considered such as martingales and martingale convergence theorems. Thus, the purpose of this study is to provide an abstract characterization of a conditional expectation operator on a space of measurable sections.

 

Keywords: Abstract characterization; conditional expectation operator; measurable section

 

ABSTRAK

Pengendalian jangkaan bersyarat memainkan peranan yang penting di dalam geometri ruang Banach. Walau bagaimanapun, isu utama adalah berkaitan dengan kewujudan pengendali jangkaan bersyarat yang membenarkan objek lain yang perlu dipertimbangkan seperti teori penumpuan martingale dan martingale. Dengan itu, tujuan kajian ini adalah untuk memberikan pencirian abstrak bagi pengendali jangkaan bersyarat di ruang bahagian yang boleh diukur.

 

Kata kunci: Bahagian yang boleh diukur; pencirian abstrak; pengendali jangkaan bersyarat
