Some results on unbounded order continuous operators
摘要
This paper investigates the class of unbounded order continuous operators between Riesz spaces. We extend the fundamental result of Bahramnezhad and Haghnejad Azar, which established that for order bounded linear functionals, unbounded order continuity is equivalent to the unbounded order continuity of its modulus. Our main contribution generalises this characterisation to operators by given some conditions on the arrival space. Furthermore, we explore the relationships between unbounded order continuous operators and other important operator classes.
