The SIAM Activity Group on Linear Algebra sponsors two prizes: the SIAM Activity Group on Linear Algebra Prize and the SIAM Activity Group on Linear Algebra Poster Competition

#### SIAM Activity Group on Linear Algebra Prize

Established in 1987, the SIAM Activity Group on Linear Algebra Prize is awarded to the author(s) of the most outstanding paper, as determined by the prize committee, on a topic in applicable linear algebra published in English in a peer-reviewed journal.
