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 Let the semicircle "C" in the upper half of the complex plan (x,y), of radius "R" centered at the origin "o". The complex number z = x + i y is represented as z = R exp{iθ}; then dz = i dθ R exp{iθ}. 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 is also useful when evaluating contour integrals. The conditions on the function are slightly weaker than in the previous result.

Applying Jordan’s lemma by closing the contour in the upper half-plane (since r > 0) we have Z eik·r k2 +µ2 d3k = 2π ir I keikr/(k +iµ) k −iµ = 2πi 2π ir keikr k +iµ k=iµ = 2π2 e−µr r. 6. Now let’s take a look at what happens when the integrand has poles that lie on the real axis, as in Shoppa sneakers och mer från Jordan på Farfetch. Damskor i många utföranden & färger. Snabb leverans Fria returer Nya stilar varje dag Robin Kothari I will talk about a classic lemma due to Jordan (1875) that is frequently used in quantum computing. Jordan's lemma says that given any two orthogonal projectors, there is a way to partition the underlying vector space into 1- and 2-dimensional subspaces that are invariant under the action of both projectors.
