Functional Analytic Methods for Heat Green Operators

Dr. Kazuaki Taira was awarded a Doctor of Science degree by the University of Tokyo (1976) and a Doctorat d'État degree by Université de Paris-Sud (Orsay) (1978), where he had studied on a French government scholarship (1976–1978). He was also a member of the Institute for Advanced Study (Princeton) (1980–1981), an associate professor at the University of Tsukuba (1981–1995), and a professor at Hiroshima University (1995–1998). In 1998, he accepted an offer from the University of Tsukuba to teach there again as a professor.  He was also a part-time professor at Waseda University (2009–2017). His current research interests are in three interrelated subjects in analysis: semigroups, elliptic boundary value problems and Markov processes.

“The book is written carefully taking into account the interests of the reader, and it can be useful for scholars who work in the theory of partial differential equations and boundary value problems.” (Vladimir Vasilyev, zbMATH 1555.35004, 2025)
