This blog we consider chapter 10 to chapter 13. [FulIT2nd] William Fulton. Intersection Theory, 2nd. Springer New York, NY. 1998. ↩ WebIllustration of Bezout's Theorem The varieties illustrated are ellipses and thus are of degree 2. According to Bezout's Theorem the number of intersection points should be 2x2=4. In Figure 1 there are four intersection points. In Figure 2 the tangent intersection at has multiplicity two so there are again four intersection points.

You can use another induction, which is useful to understand the Extended Euclidean algorithm: it consists in proving that all successive remainders in the algorithm satisfy a Bézout's identity whatever the number of steps, by a finite induction or order 2. a = 1 ⋅ a + 0 ⋅ b, = 0 ⋅ a + 1 ⋅ b. At the i -step, you have r i − ...
