Conjugacy classes and characters in some quotients of the Nottingham group
The author calculates the number of conjugacy classes, the degrees of irreducible characters together with their multiplicities in the natural quotients of the Nottingham group over an arbitrary finite field of \(q\) elements for the quotients of order \(q^t\) with \(p+2\leq t\leq 2p+1\), where \(p\) is the characteristic of the field. The case \(t\leq p+1\) was investigated earlier by \textit{I.~O.~York} [Proc. Edinb. Math. Soc., II. Ser. 33, No. 3, 483-490 (1990; Zbl 0723.20010)].
