This paper investigates the distribution function and nonincreasing rearrangement of $$\mathbb{B}\mathbb{C}$$
B
C
-valued functions equipped with the hyperbolic norm. It begins by introducing the concept of the distribution function for $$ \mathbb{B}\mathbb{C}$$
B
C
-valued functions, which characterizes valuable insights into the behavior and structure of $$\mathbb{B}\mathbb{C}$$
B
C
-valued functions, allowing to analyze their properties and establish connections with other mathematical concepts. Next, the nonincreasing rearrangement of $$\mathbb{B}\mathbb{C}$$
B
C
-valued functions with the hyperbolic norm are studied. By exploring the nonincreasing rearrangement of $$\mathbb{B}\mathbb{C}$$
B
C
-valued functions, it is aimed to determine how the hyperbolic norm influences the rearrangement process and its impact on the function’s behavior and properties.
