Frobenius method

Common card · No. 415931

In mathematics, the method of Frobenius, named after Ferdinand Georg Frobenius, is a way to find an infinite series solution for a linear second-order ordinary differential equation of the form z 2 u ″ + p ( z ) z u ′ + q ( z ) u = 0 {\displaystyle z^{2}u''+p(z)zu'+q(z)u=0} with u ′ ≡ d u d z {\textstyle u'\equiv {\frac {du}{dz}}} and u ″ ≡ d...
