Conics - a Poor Man's Elliptic Curves

Abstract
The aim of this article is to show that the arithmetic of Pell conics admits a description which is completely analogous to that of elliptic curves: there is a theory of 2-descent with associated Selmer and Tate-Shafarevich groups, and there should be an analog of the conjecture of Birch and Swinnerton-Dyer.
If elliptic curves seem tricky, you can follow the same idea with conics https://arxiv.org/pdf/math/0311306.pdf https://www.researchgate.net/profile/Shailesh-Shirali/public...
