### hBLinear Calculus over Function Fields, by Anatoly N. Kochubei

We define analogues of higher derivatives for $F_q$-linear functions over
the field of formal Laurent series with coefficients in $F_q$. This
results in a formula for Taylor coefficients of a $F_q$-linear
holomorphic function, a definition of classes of $F_q$-linear smooth
functions which are characterized in terms of coefficients of
their Fourier-Carlitz expansions. A Volkenborn-type integration
theory for $F_q$-linear functions is developed; in particular, an
integral representation of the Carlitz logarithm is obtained.
