Any good anagrams for kelvin function?

Noun.

A class of special functions usually denoted as two pairs of functions ber(x), bei(x), ker(x) and kei(x) with variable x and given order number n. The former two functions ber(x) and bei(x) respectively correspond to the real part and the imaginary part of the Kelvin differential equation's solution that can be expressed with the Bessel function of the first kind J(x), and the latter ker(x) and kei(x) correspond to those that can be expressed with the modified Bessel function of the second kind K(x).
