1. Homework Statement

1. Homework Statement

This question is from book Afken Weber, Mathematics for Physicist.

An operator ##T(t + ε,t)## describes the change in the wave function from t to t + ##\epsilon## . For ##\epsilon## real and small enough so that ##\epsilon^{2}## may be neglected,

$$T(t+\epsilon, t)= 1 - \frac{i * \epsilon* \text H(t)}{h} $$

WHERE H(t) is hamiltonian, i is complex number ##i = \sqrt-1##, h is constant. Prove that if

- T is unitary matrix, H is hermitian
- H is hermitian, T is Unitary

How do I prove this Property. Also what is structure of right hand side of the equation i.e how do I visualise R.H.S of equation?
