| dbo:abstract | Alan Gaius Ramsay McIntosh (* 1942 in Sydney, † August 8, 2016 ) was an Australian mathematician who dealt with analysis (harmonic analysis, partial differential equations). He was a professor at the Australian National University in Canberra. McIntosh studied at the University of New England with a bachelor's degree in 1962 (as a student he also received the University Medal ) and PhD in 1966 with Frantisek Wolf at the University of California, Berkeley, ( Representation of Accretive Bilinear Forms in Hilbert Space by Maximal Accretive Operator ). In Berkeley, he was also a student of Tosio Kato. As a post-doctoral student, he was at the Institute for Advanced Study and from 1967 he taught at Macquarie University and from 1999 at the Australian National University. In 2014 he became emeritus. McIntosh was involved in solving the in the theory of singular integral operators. In 2002, he solved with Pascal Auscher, Michael T. Lacey, and Steve Hofmann the open Kato root problem for elliptic differential operators. He also deals with singular integral operators, boundary value problems of partial differential equations with applications (such as scattering theory of the Maxwell equations in irregular areas), spectral theory and functional calculus of operators in Banach spaces, analysis with Clifford algebras, barriers for the heat kernel equation and functional calculus for elliptic partial differential operators. In 1986 he became a fellow of the Australian Academy of Science, whose Hannan Medal he received in 2015. In 2002 he received the from Macquarie University. (en) Alan Gaius Ramsay McIntosh (* 17.

Er war Hochschullehrer an der Australian National University in Canberra. McIntosh studierte an der University of New England mit dem Bachelor-Abschluss 1962 (als Student erhielt er auch die Universitätsmedaille) und wurde 1966 bei an der University of California, Berkeley, promoviert (Representation of Accretive Bilinear Forms in Hilbert Space by Maximal Accretive Operators). In Berkeley war er auch ein Schüler von Tosio Kato. Als Post-Doktorand war er am Institute for Advanced Study und ab 1967 lehrte er an der Macquarie University und ab 1999 an der Australian National University. 2014 wurde er emeritiert. McIntosh war an der Lösung der Calderon-Vermutung in der Theorie singulärer Integraloperatoren beteiligt. 2002 löste er mit Pascal Auscher, Michael T. Lacey, Philippe Tchamitchian und Steve Hofmann das seit 1953 offene Kato-Wurzelproblem für elliptische Differentialoperatoren. Außerdem befasst er sich mit Singulären Integraloperatoren, Randwertproblemen partieller Differentialgleichungen mit Anwendungen (wie Streutheorie der Maxwellgleichung in irregulären Gebieten), Spektraltheorie und Funktionalkalkül von Operatoren in Banachräumen, Analysis mit Cliffordalgebren, Schranken für die Wärmeleitungsgleichung (Heat Kernel) und Funktionalkalkül für elliptische partielle Differentialoperatoren. 1986 wurde er Mitglied der Australian Academy of Science, deren Hannan Medal er 2015 erhielt. 2002 erhielt er die Moyal Medal der Macquarie University.
