The dissetation deals with the inverse problem of identification of local volatilities from given option price data. The used separation between purely time- and purely price-dependent volatilities enables a detailed mathematical analysis of the corresponding inverse problems. Those are formulated in proper Banach spaces (Hilbert spaces) as operator equations. The unique solvability of these equations are examined. Because the solutions doesn't depend continuously form the given data, possibilities of regularization are discussed. In particular the nonlinear Tikhonov regularization and its applicability to the corresponding problems plays the leading part in these investigations. Detailed numerical studies illustrate these considerations an...
