Title: Half a mathematical lifetime with Gavin 

Abstract: 

University teachers tend to treat their students as their "academic children".  Gavin
was my academic older brother.  

This is a unique and very sad occasion for me and I feel privileged to be asked to give
this talk at this time.  I intend to summarise, insofar as is possible in a single
lecture, the mathematical work of Gavin Brown, whose untimely death at Christmas left us
all feeling a profound sense of loss and, in my case, of missed opportunities.  Over the
month or so since his death, many memories of the wonderful and intense times we spent
together have returned.  For about twenty years of his and my careers, we worked closely
together, publishing around 40 papers on various topics in harmonic analysis.  In many
ways, this period was core to the later research of both of us.  Inevitably then this
talk will, to a significant extent, be a presentation of that joint work.  Later in the
talk I will discuss Gavin’s work, alone and with others, after our collaboration had run
its course.  

The key topics I will discuss are Measure Algebras, Bernoulli Measures, Riesz products,
Normality and the Schmidt conjecture, G-measures, Sum-Set Inequalities, and
Trigonometric Inequalities, since these define most of Gavin’s areas of interest over
his mathematical career, though I will touch on some other topics where I think that
Gavin made a rather unique contribution.  

It would be inappropriate on this special occasion to spend much time discussing the
technical details of his work.  Rather I will use the mathematics as a backdrop for
reminiscing about the man and what it was like to work with him.
