Thomas Ransford (born 1958) is a British-born Canadian mathematician, known for his research in spectral theory and complex analysis. He holds a Canada Research Chair in mathematics at Université Laval.[1]
Ransford earned his Ph.D. from the University of Cambridge in 1984.[2]
He was a fellow of Trinity College, University of Cambridge, from 1983 to 1987.[3] [4]
In addition to over 90 research papers on mathematics, he has written a research monograph "Potential Theory in the Complex Plane" in 1995, and the graduate book "A Primer on the Dirichlet Space" with Omar El-Fallah, Karim Kellay and Javad Mashreghi in 2014 https://www.cambridge.org/core/books/primer-on-the-dirichlet-space/11E839FD715CC1B10A73FFD8974C2162.
He has proved results on potential theory, functional analysis, the theory of capacity, and probability. For example, with Javad Mashreghi he proved the Mashreghi–Ransford inequality. He also derived a short elementary proof of Stone–Weierstrass theorem http://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=2088612&fileId=S0305004100062204.
