Derivative of wronskian

In mathematics, the Wronskian (or Wrońskian) is a determinant introduced by Józef Hoene-Wroński (1812) and named by Thomas Muir (1882, Chapter XVIII). It is used in the study of differential equations, where it can sometimes show linear independence in a set of solutions. See more The Wronskian of two differentiable functions f  and g is W(f, g) = f g′ – g f′. More generally, for n real- or complex-valued functions f1, …, fn, which are n – 1 times differentiable on an interval I, the Wronskian W(f1, … See more • Variation of parameters • Moore matrix, analogous to the Wronskian with differentiation replaced by the Frobenius endomorphism over … See more If the functions fi are linearly dependent, then so are the columns of the Wronskian (since differentiation is a linear operation), and the Wronskian … See more For n functions of several variables, a generalized Wronskian is a determinant of an n by n matrix with entries Di(fj) (with 0 ≤ i < n), where each Di is some constant coefficient linear partial differential operator of order i.

Evidently, the Wronskian must not be equal to zero ( W ≠ 0) for a solution to exist. For examples, the two solutions X 1 ( t) = A sin ω t, X 2 ( t) = B sin ω t, have a zero Wronskian at t = t 0, as can be shown by computing
