Schrodingers derivation of wave mechanics

Schrodinger concludes his first paper (1926) by stating that the function be such as to make the Hamilton integral  

The quantity T q,d l//8q) is the kinetic energy expressed in terms of the momentum as in the first term on the right-hand side of eqn (5.47) that is, as p /2m, and V is the potential energy. Schrodinger considered specifically the problem of the hydrogen atom for which the explicit form of the functional is 

We shall allow for the possibility of ij/ being complex in our review of Schrodinger s work. The functions ip and ip are treated as independent 

To this must be added the effect of the constraint on the normalization of which is written as 

Eqn (5.56) is multiplied by a factor a and then added to the variation of Requiring the resultant variation, which is labelled to be stationary
