DESCRIPTION:Following an example set by Slepyan\, it proves possible to em
 ploy the Wiener-Hopf method to obtain exact solutions for fracture and fri
 ction problems at the atomic scale. I will describe a number of physical p
 henomena that have been analyzed in this way. These include the velocity g
 ap and micro-branching instability for dynamic cracks\, a connection of fr
 iction with self-healing pulses\, and resolution of the energy transport p
 aradox for supersonic cracks.
