Et lemma (flertall lemma eller lemmaer) er i matematikk en mindre hjelpesetning som brukes til å bevise et større teorem. [2] [3] Når en skal bevise et større teorem kan det være nødvendig å bygge opp beviset ved hjelp av en rekke mindre resultat.

För ordformen, se Lemma (ordform). Ett lemma eller en hjälpsats är i ett bevis, ett resultat av mindre betydelse, som är ett delsteg i bevisandet av en viktigare sats. Vad som karakteriserar ett lemma är inte väldefinierat och varierar mellan olika framställningar. Ett känt lemma är Jordans lemma.

Lemma 1.5. There is a bijection between Z/2Z-graded Lie algebras and symmetric pairs, i.e., pairs (g,σ) of a Lie algebra We will now review some of the recent material regarding the Riemann- Lebesgue Lemma, Jordan's Theorem, and Dini's Theorem. We began on the Lebesgue View Notes - Notes -271 from MATH Math 121 at Harvard University. CHAP.

For <0, the same conclusion holds for the semicircular contour C Rin the lower half-plane. Indeed, Z CR f(z)ei zdz= iR Z ˇ 0 f Rei Jordan's lemma can be stated as follows: let be an analytic function in the upper half of the complex plane such that on any semicircle of radius in the upper half-plane, centered at the origin. Then, for , the contour integral as [1, 2]. Jordan's Lemma is a small but important mathematical result that is useful in contour integration.In complex analysis we often wish to integrate functions around large semicircles in the complex plane, and Jordan's lemma provides useful information about how these integrals behave.

Jordan's lemma yields a simple way to calculate the integral along the real axis of functions f(z) = e i a z g(z) holomorphic on the upper half-plane and continuous on the closed upper half-plane, except possibly at a finite number of non-real points z 1, z 2, …, z n.
