A Friday Evening on Lagrangian and Weak formulation
Why the talk?
You might have seen the Euler-Lagrange equation in PH1010 course. But how did it come out of the Law of Action? Well, turns out it is not true all the time.
Hmm.. so how do simulation engines actually solve it?
What did we cover?
It was a 2 hour talk where we went through mathematical “loopholes” that let us differentiate the undifferentiable, concept of Sobolov Spaces, “Hat” functions, Beltrami’s Indentity and applications of these concepts in physics.
