Category:Ber Function

This category contains results about Ber Function.
Definitions specific to this category can be found in Definitions/Ber Function.

Let $J_n$ denote the Bessel function of the first kind.

The Ber function is defined as:

$\map {\Ber_n} x = \map \Re {\map {J_n} {x \map \exp {\dfrac {3 \pi i} 4} } }$

where:

$\exp$ denotes the exponential function

$x$ is real

$\map \Re z$ denotes the real part of $z$.
