Standard requirements that the wavefunction should obey

3 Standard requirements that the wavefunction should obey 

In all cases, the wavefunction i/t(jc, y, z) as the solution of the SchrOdinger equation should possess some properties that themselves play an important role in quantum mechanics. Before describing the methods for solving Schrodinger equation, we have to analyze the standard requirements (conditions) that a wavefunction should obey these requirements result from the type of equation and the physical sense of the functions. This especially concerns cases when the problem should be divided into pieces because of the complexity of the potential distribution. 

Furthermore, as we know that the micro-object really exists in the whole region, the wavefunction i/ (x, y, z) should obey the normalization condition. The total probability of finding a particle in the whole range of variable must be unity, i.e., 

The properties mentioned are called the standard requirements (conditions) that the wavefunction should obey. They result from the type of equation and physical sense of these functions.
