What a wonderful lecturer Professor Zwiebach is - I'm not sure I've come across a teacher so clear and engaging.

The assumption of the series seems quite random to me. I don't know why exactly this works...

I've wondered the same thing. Must be derived from QFT or some higher-level quantum theory I don't know yet.

I think I might know why, but correct me if I missed something. Lambda is just a parameter that changes the Hamiltonian slightly, so it makes sense that for each energy of the original Hamiltonian and its corresponding eigenstate, a small change in lambda will result in a small change in both said energy and state. Therefore you can think of the energy and state as functions of lambda: you input a value of lambda between zero and one, and you get the corresponding energy and state. Regardless of what these functions are (ie how changing lambda affects things), every function has a power series expansion, which will be a constant plus a lambda term plus a lambda squared term etc. If you need a refresher, watch this kzbin.info/www/bejne/aZWZdaagfqetgJY

Whats the delta, he wrote before the Halitonian H ?

It is to denote the perturbed hamiltonian u can write H' instead...its not the dirac delta.

Currently not available in video format but is available in written at: ocw.mit.edu/courses/physics/8-251-string-theory-for-undergraduates-spring-2007/. There is video of a string theory course that focuses on holographic duality (Hong Liu. 8.821 String Theory and Holographic Duality. Fall 2014)-- KZbin playlist: kzbin.info/aero/PLUl4u3cNGP633VWvZh23bP6dG80gW34SU MIT OCW materials: ocw.mit.edu/8-821F14. Best wishes on your studies!
