Stability of a flexible missile described by asymptotics of the eigenvalues of fourth order boundary value problems

Bertin Zinsou

Fourth order problems, with the differential equation $y^{(4)}-(g{y}^{\prime }{)}^{\prime }={\lambda }^{2}y$, where $g\in C^1[0,a]$ and $a>0$, occur in engineering on stability of elastic rods. They occur as well…
