Abstract:
A new representation is proved of the solutions of initial boundary value problems for the equation of the form $u_{xx}(x,t)+r(x)u_{x}(x,t)-q(x)u(x,t)=u_{tt}(x,t)+\mu(x)u_{t}(x,t)$ in the section (under boundary conditions of the 1st, 2nd, or 3rd type in any combination). This representation has the form of the Riemann integral dependent on the $x$ and $t$ over the given section.
