Research Interests

My field within mathematics is mathematical analysis, in particular complex and harmonic analysis. In complex analysis, I took part in the studies of Hardy spaces during the 1960's and 70's and in particular studied the algebra of bounded analytic functions. In harmonic analysis, I have studied the convergence of Fourier series. During later years, I have used analytic methods in the study of low-dimensional dynamical systems.
