In Memoriam: Peter Benjamin Borwein (1953-2020)

Peter Borwein had wide-ranging mathematical interests, and was a pioneer in computational and experimental investigations in many areas. We fondly recall some of his interests and contributions in a number of topics in analysis, number theory, and other areas, especially work where computation and experimentation played an important role. This includes his work on a number of extremal problems regarding Littlewood polynomials and other families of integer polynomials with restricted coefficients, questions regarding the Mahler measure of an integer polynomial, problems on merit factors and Barker sequences, the Prouhet-Tarry-Escott problem, problems of P & oacute;lya and Tur & aacute;n regarding sums of the Liouville function, and questions in combinatorial geometry regarding arrangements of points and lines.
