Abstract: In this paper, for the parabolic equation ${u_t} = \Delta u + g\left ( {x, u} \right ), \left ( {x, t} \right ) \in \\ \Omega \times \left ( {0, T} \right )$, with nonlocal boundary conditions $u\left | {_{\partial \Omega }} \right . = \int _{\Omega } f\left ( {x, y} \right )u\left ( {y, t} \right )dy$, we establish the comparison theorem and local existence of the solution. We also discuss its long time behavior.
