Workshop on Numerical Ranges and Numerical Radii

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, dilation theory, control theory, numerical analysis, quantum information science.{{cite book|last1=Bhatia|first1=R.|title=Matrix Analysis|date=1997|publisher=Springer-Verlag|isbn=978-0387948461|pages=349|url=https://www.springer.com/us/book/9780387948461}}

In the early 1970s, numerical range workshops were organized by Frank Bonsall 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.{{cite journal|editor-last1=Ando|editor-first1=T.|editor-last2=Li|editor-first2=C.K.|title=Special issue devoted to WONRA|journal=Linear and Multilinear Algebra|date=1994|volume=37|issue=1–3}}
