The Wikipedia has the following information about this codepoint:
In the mathematical field of complex analysis, the Bloch space, named after French mathematician André Bloch and denoted B {displaystyle {mathcal {B}}} or ℬ, is the space of holomorphic functions f defined on the open unit disc D in the complex plane, such that the function
 ( 1 −  z  2 )  f ′ ( z )  {displaystyle (1z^{2})f^{prime }(z)}
is bounded. B {displaystyle {mathcal {B}}} is a Banach space, with the norm defined by
 ‖ f ‖ B =  f ( 0 )  + sup z ∈ D ( 1 −  z  2 )  f ′ ( z )  . {displaystyle f_{mathcal {B}}=f(0)+sup _{zin mathbf {D} }(1z^{2})f'(z).}
This is referred to as the Bloch norm and the elements of the Bloch space are called Bloch functions.
