Siegel identity

In mathematics, Siegel's identity refers to one of two formulae that are used in the resolution of Diophantine equations.

Statement

The first formula is

The second is

Application

The identities are used in translating Diophantine problems connected with integral points on hyperelliptic curves into S-unit equations.

gollark: They split up BT-the-ISP and BT-the-company-with-some-wires a while ago.
gollark: In the UK you can choose from several ISPs using the same terrible VDSL/ADSL lines!
gollark: That probably comes under consent, unless you ask to be murdered?
gollark: Which everyone can easily do on their own, of course.
gollark: I'm saying this because if you happen to be annoyed at your provider charging more money for Netflix or something you may not be able to change to a better one.
