In this paper, some linear integral-differential equations, appearing in dealt problems for viscoelastic rods, (See [l ]are treated system-alically and generally.These equations are of forms (l. 1), (1. 3), (1.4), (2.1), (3.1), (3.4), (3. 7)and (3.8), some of which are libely not discussed in the literature, the others are not argued so tho-roughly as here. |
