Kabanikhin (Sobolev Institute of Mathematics, Russia) ``Discrete and continuous Gelfand-Levitan method in multidimensional inverse problems'' ¡ã¸¦µæÈ¯É½Í׻ݡä The multidimensional analog of Gelfand-Levitan method of solving inverse problems for hyperbolic equations is considered. The discrete analog of multidimensional hyperbolic inverse problem is the nonlinear system of algebraic equations. This system is proved to be equivalent to the properly chosen system of linear algebraic equations. Applications to siesmic and acoustic inverse problems are discussed.
