He did scientific research in the area of combinatorics and he contributed to the development of the symbolic language of mathematics. He discovered the generalized form of the Lagrange inversion theorem. He corresponded and published with Joseph Louis Lagrange and Carl Hindenburg.

Iterate function composition notation

The compositional notation $f^n$ for the Template:Nowrap iterate $f^n:=f\circ f^{n-1}=\stackrel{n\text{ times}}{\overbrace{f\circ f\circ \cdots \circ f}}$ of function $f$ was originally introduced by BürmannTemplate:Citation needed and later independently suggested by John Frederick William Herschel in 1813.
