A class of Gorenstein Artin algebras of embedding dimension four
(University of MissouriColumbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Let R be a polynomial ring in n variables and I be a homogeneous ideal in R. Such an ideal I is called Gorenstein if the quotient R/I has a free ... 
Trace formulae in finite von Neumann algebras
(University of MissouriColumbia, 2007)The dissertation is devoted to some aspects of spectral perturbation theory in the context of finite Von Neumann algebras. The central results are analogs of the BirmanSchwinger principle and the BirmanKrein formula for ... 
Transference and Szego's theorem for measure preserving representations
(University of MissouriColumbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] We prove analogues of the classical Szeg̈o's theorem concerning approximation by polynomials on the unit circle, and Jensen's inequality involving the ... 
Volatility estimation and price prediction using a hidden Markov model with empirical study
(University of MissouriColumbia, 2007)This work provides a solid development of a hidden Markov model (HMM) from the economic insight to the mathematic formulation. In this model, we assume both drift and volatility of the security return process are driven ...
