A survey of my joint research with Gavin Brown

I have been collaborating with Gavin Brown since 1990. Our research mainly concerns the positivity of trigonometric sums and Jacobi polynomial sums. It also concerns multiple trigonometric sums and the convergence of the linear means of multiple Fourier series and Fourier-Laplace series. The present report is a survey on our joint results.
