Relativistic string with massive ends

The classical and quantum theory is discussed for the relativistic string with point masses at its ends. The dynamical equations are solved for the class of motions when the time evolution parameter tau is proportional to proper times of the string ends. The solution of the linear boundary value problem is given by the Fourier series. Constraints on the Fourier amplitudes resulting from the orthogonal gauge differ essentially from the Virasoro conditions for the free string. The string mass, momentum and angular momentum are found
