In morphology and lexicography, a lemma (pl.: lemmas or lemmata) is the canonical form, [1] dictionary form, or citation form of a set of word forms. [2] In English, for example, break , breaks , broke , broken and breaking are forms of the same lexeme , with break as the lemma by which they are indexed.
Burnside's lemma also known as the Cauchy–Frobenius lemma; Frattini's lemma (finite groups) Goursat's lemma; Mautner's lemma (representation theory) Ping-pong lemma (geometric group theory) Schreier's subgroup lemma; Schur's lemma (representation theory) Zassenhaus lemma
For example, in the English language, run, runs, ran and running are forms of the same lexeme, which can be represented as RUN. [note 1] One form, the lemma (or citation form), is chosen by convention as the canonical form of a lexeme. The lemma is the form used in dictionaries as an entry's headword. Other forms of a lexeme are often listed ...

Medical literature is the scientific literature of medicine: articles in journals and texts in books devoted to the field of medicine. Many references to the medical literature include the health care literature generally, including that of dentistry , veterinary medicine , pharmacy , nursing , and the allied health professions .
Burnside's lemma, a counting technique in group theory, was discovered by Augustin Louis Cauchy, or possibly others. William Burnside originally attributed it to Ferdinand Georg Frobenius. Ironically, Burnside made many original contributions to group theory, and Burnside's Lemma is sometimes jokingly referred to as "the lemma that is not ...
A paper of George Lusztig and David Kazhdan pointed out that orbital integrals could be interpreted as counting points on certain algebraic varieties over finite fields. Further, the integrals in question can be computed in a way that depends only on the residue field of F ; and the issue can be reduced to the Lie algebra version of the orbital ...
In mathematics and other fields, [a] a lemma (pl.: lemmas or lemmata) is a generally minor, proven proposition which is used to prove a larger statement. For that reason, it is also known as a "helping theorem " or an "auxiliary theorem".
