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.
2 Jordan’s Lemma It turns out that the above argument is wasteful; we only used that je ayj 1 for positive y, but most of the time, it is actually much smaller! By doing a more delicate calculation, we can make the above argument work in the more general case when deg(Q) deg(P)+1, rather than 2, and this is quite useful.
