Mathematical work The Carlitz module is generalized by the Drinfeld module An identity regarding Bernoulli numbers Carlitz wrote about Bessel polynomials He introduced Al-Salam–Carlitz polynomials. Carlitz' identity for bicentric quadrilaterals He conjectured the Carlitz-Wan conjecture, later proved by Daqing Wan.

Publications

Leonard Carlitz published about 771 technical papers comprising approximately 7,000 pages. The effort to edit his collected works, undertaken originally by Professor John Brillhart, is ongoing.

Carlitz' exceptional productivity is described by David Hayes as follows:

About 160 articles by Carlitz are about finite fields. The textbook by Rudolf Lidl and Harald Niederreiter on the topic has 141 articles authored or coauthored by Carlitz in its reference list.
