Delta invariant

In mathematics, in the theory of algebraic curves, a delta invariant measures the number of double points concentrated at a point. It is a non-negative integer. Delta invariants are discussed in the "Classification of singularities" section of the algebraic curve article. (Wikipedia).

Limits 1b - Delta-Epsilon Formulation

Calculus: We present the delta-epsilon definition of a limit, explain the various parts pictorially, and show how to choose delta when presented with a given epsilon. We show that delta = .1 works for f(x) = x^2 at x_0 =2 when epsilon = 1/2.

Epsilon delta limit (Example 2)

In this video, I calculate the limit as x goes to 3 of x^2, using the epsilon-delta definition of a limit.

Epsilon delta limit (Example 3): Infinite limit at a point

This is the continuation of the epsilon-delta series! You can find Examples 1 and 2 on blackpenredpen's channel. Here I use an epsilon-delta argument to calculate an infinite limit, and at the same time I'm showing you how to calculate a right-hand-side limit. Enjoy!

Lecture 02 | From Particles to Fields

In this lecture, I introduce states describing any number of particles and define operators acting on these states. I argue that causality requires that the theory be written in terms of "observables," local Hermitian operators that commute at spacelike positions. This leads us to a theory
