Abstract

A mixed problem for the equation

                                                $ Lu\equiv (t^{\alpha}u'')''+\alpha u=f $   (1)

is considered. Firstly, the weighted Sobolev spaces $W_\alpha^2,~ W_{\alpha}^2(0),~W_{\alpha}^2(b)$ and the generalized solution to equation (1) are defined. Next, the existence and uniqueness of the generalized solution for the mixed problem is studied, as well as the description of the spectrum of corresponding operator is given.
