Noncommutative Analysis

Month: January, 2020

Janos Aczel (1924-2020)

I was saddened to find out that Janos Aczel passed away earlier this month. In my early days, after Boris Paneah got me hooked on functional equations, Aczel’s books caught my eye. Since then I am a fan of his. In particular, I was drawn by a small booklet by him whose title I am not able to reconstruct, and his two larger books “Lectures on Functional Equations and Their Applications” (1966) and “Functional Equations in Several Variables” (1987, co-authored with, Dhombres), which for a couple of years were to me among the most interesting and useful books I knew.

I have two stories two tell about Janos.

My talks at NCGA Bhubaneswar

This week I am giving a series of five lectures on dilation theory in the workshop Noncommutative Geometry and its Applications , at NISER Bhubaneswar (India). I am putting my talks up here in case anybody would like to see them (and also as backup, in case my stick doesn’t work).

Lecture number 4.

Lecture number 5.

(Lectures 1,2,3 were board talks).
