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
