This thesis extends the LIBOR market model of Wu and Zhang. This model separates the forward rate volatility into a deterministic factor, specific to each forward rate, and a stochastic term common to all rates. Since the stochastic term has a structure similar to the volatility process in the Heston model, following a similar approach a semi-analytical pricing formula for Caplets and Swaptions is obtained.
