In this paper, we derive a trace formula for self adjoint fourth order differential operator with bounded operator coefficient in the separable Banach space. Compared with the regularized trace ...
The equation y$^{\prime \prime}$ + [$\lambda $ - q(x)]y = 0 on (0, $\infty $) or (-$\infty $, $\infty $), in which q(x) $\rightarrow \infty $ as x $\rightarrow \infty ...
