The representations are given in the form of integral convolutions involving a Green's function for the parabolic heat conduction equation, as well as Green's function for the isothermal elastodynamics. In this paper, we present a converted closed-form analytical solution for both free and forced vibration responses of a damped axially moving wire, as well as the boundary value problems, based on the Green's function. The primary use of Green's functions in mathematics is to solve inhomogeneous boundary value problems. Semi-infinite cylindrical domains with curvilinear surfaces placed at infinity and subject to mixed boundary conditions on the plane boundaries are obtained. The method is to use Green's identity and Green's second formula to transform the problem to another specialized Dirichlet boundary-value problem.

In the process, we naturally derive Green's function. Vector identities, Directional derivatives, Line, Surface and Volume integrals, Stokes, Gauss and Green's theorems. Established in 1882 at Lahore which is now in Pakistan, the Panjab university campus spreads over 550 acres of vast green land and has 188 affiliated institutions in Punjab and regional centers in Kauni, Muktsar, Ludhiana and Hoshiarpur. Form solutions for any such domains, thus substitutes for a variety of methods (such as Green's functions approximation by least squares techniques, conformal mapping or solution of the boundary integral equation by iterative methods) avoiding the cumbersome computational methods of finite differences and finite elements.
