Regular Singular Point - Hermite Differential Equation

Hermite Differential Equation

One encounters this ordinary second order differential equation in solving the one dimensional time independent Schrödinger equation

for a harmonic oscillator. In this case the potential energy V(x) is:

This leads to the following ordinary second order differential equation:

$\frac {d^2 f} {dx^2} - 2 x \frac {df} {dx} + \lambda f = 0.$

This differential equation has an irregular singularity at ∞. Its solutions are Hermite polynomials.

Famous quotes containing the words differential and/or equation:

“But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
—Antonin Artaud (1896–1948)

“A nation fights well in proportion to the amount of men and materials it has. And the other equation is that the individual soldier in that army is a more effective soldier the poorer his standard of living has been in the past.”
—Norman Mailer (b. 1923)
