In this talk, a completelynew integral equation for the price of an American put option as well as itsoptimal exercise price is presented. Compared to existing integral equationsfor pricing American options, the newly derived integral equation for pricingAmerican options has some clear advantages over those proposed in the past withthe following two unique features: i) it is in a form of one-dimensionalintegral, which means that it has a great advantage in terms of substantiallyincreasing the speed with which values of an American option can be numericallycomputed. ii) it is in a form free from any discontinuity and singularitiesassociated with the optimal exercise boundary (at least as far as solving theintegral equation is concerned); the computational accuracy and efficiency canthus be enhanced. These rather unique features have led to a significantenhancement of the computational accuracy and efficiency as demonstratedthrough some examples.

This talk presents the directand inverse scattering problem associated with a time-harmonic randomSchroedinger equation with a Gaussian white noise source term. We establish thewell-posedness of the direct scattering problem and obtain three uniquenessresults in determining the variance of the source term, the potential and themean of the source term, sequentially, by the corresponding far-fieldmeasurements. The first one shows that a single realization of the passive scatteringmeasurement can uniquely recover the variance of the source term, withoutknowing the other two unknowns. The second shows that if active scatteringmeasurement is further used, then a single realization can uniquely recover thepotential function without knowing the source term. The last one shows that iffull measurements are used, then both the potential and the random source canbe uniquely recovered.
