Workshop on Numerical Ranges and Numerical Radii (WONRA) is a biennial workshop series on
numerical ranges and numerical radii which began in 1992.
About
Numerical ranges and numerical radii are useful in the study of matrix and operator theory.
These topics have applications in many subjects in pure and applied mathematics, such as
quadratic forms,
Banach spaces
In mathematics, more specifically in functional analysis, a Banach space (pronounced ) is a complete normed vector space. Thus, a Banach space is a vector space with a metric that allows the computation of vector length and distance between vect ...

control theory
Control theory is a field of mathematics that deals with the control of dynamical systems in engineered processes and machines. The objective is to develop a model or algorithm governing the application of system inputs to drive the system to a ...

numerical analysis
Numerical analysis is the study of algorithms that use numerical approximation (as opposed to symbolic manipulations) for the problems of mathematical analysis (as distinguished from discrete mathematics). It is the study of numerical methods th ...

History
In the early 1970s, numerical range workshops were organized by
Frank Bonsall
Frank Featherstone Bonsall FRS (31 March 1920, Crouch End, London – 22 February 2011, Harrogate) was a British mathematician.
Personal life
Bonsall was born on 31 March 1920, the youngest son of Wilfred C Bonsall and Sarah Frank. His older bro ...
and John Duncan. More activities were started in early 1990s, including the biennial workshop series, which began in 1992,
and special issues devoted to this workshop were published.
