comment What is the idea behind counting the number of excited states and the representation of a group ?
No, how to extend it for higher excited states. And how to identify such a mapping uniquely.

Hi, I understood it for the second/third excited states, I wanted to know how it generalizes.

comment Basis in quantum mechanics
It would be better if you give the reference, so that one can know in which context it is told.

comment Perturbation in Supersymmetric Quantum Mechanics.
@LuboŇ°Motl : Sir, do you mean if I expand $Q$ perturbatively in $\lambda$, and determine ground state upto some order 'n',and then take the Hamiltonian upto that order, and find that expectation value is zero. I understand that I can find uniquely the ground state by demanding it to be annihilated by Q, therefore the above result should hold true. I was just curious if I would be able to show it in various orders of perturbation.

comment From Lagrangian to Hamiltonian in Fermionic Model
Sorry for the sloppy way of posting the question. I think I was in a haste while doing so, actually Lagrangian does have a summation over all the indices.
