We discuss extensions of recently proposed semidefinite optimization methods for atomic decomposition and 1-norm minimization over infinite dictionaries of complex exponentials. We show that techniques related to the Kalman-Yakubovich-Popov lemma in linear system theory provide simple constructive proofs of these semidefinite formulations. This ...

Mean field game theory has been developed largely following two routes by different researchers. One route, called the direct approach, starts by solving a large-scale game and next derives a set of limiting equations. The second route is to apply mean field approximations and formalize a fixed point problem by obtaining the best response of a r...

Fractional Brownian motions (FBMs) denote a family of Gaussian processes indexed by the Hurst parameter H ˆˆ (0, 1) that can be empirically justified as models for noise in many physical systems. While this family includes Brownian motion (H = 1/2), the other Gaussian processes in this family are neither Markov nor semimartingales. Thus many of ...

Some control problems are explicitly solved for bilinear evolution equations where the noise is a Gauss-Volterra process. The Gauss-Volterra noise processes are obtained from the integral of a Brownian motion with a suitable kernel function. These noise processes include fractional Brownian motions with Hurst parameter from (1/2, 1), Liouville f...
