Eval4SASO Workshop. IEEE SASO. September, 2012. Problem: What is “Resilience”?. Which of these two systems is better?. Prior work has few quantitative metrics, and none are comparable and feasible to compute. Time Independent Theory. A Necessity:. Exactly solvable problems are very few and do not really represent a real physical system completely.. In many cases, the primary interaction on the system maybe exactly solvable and is hence the dominant contribution.. Estimator of Primordial Perturbation in Equilateral . Type Non-Gaussian Models.

Perturbation Theory is an important and powerful method in physics. It enables us to make progress when a physical system is too complicated to be analyzed exactly. The essential idea is to solve the behavior in steps. First we approximate the system by some simple Hamiltonian whose Schrödinger equation we know how to solve. Then we add the bit missed out, and use perturbation theory to calculate how our previous results (energy . Lecture 12. P. erturbation theory examples. HWK 4 is due Wednesday.. 150. Non-degenerate.
