## Involve: A Journal of Mathematics

Involve showcases and encourages high-quality mathematical research involving students from all academic levels. The editorial board consists of mathematical scientists committed to nurturing student participation in research.

Submissions in all mathematical areas are encouraged. All manuscripts accepted for publication in Involve are considered publishable in quality journals in their respective fields, and include a minimum of one-third student authorship. Submissions should include substantial faculty input; faculty co-authorship is encouraged.

Bridging the gap between the extremes of purely undergraduate-research journals and mainstream research journals, Involve provides a venue to mathematicians wishing to encourage the creative involvement of students. Involve is a great resource for inspiring mathematical exploration in a new generation, and an opportunity for students who are serious about their research.

Involve publishes 5 issues per year, for an expected total of about 900 pages.
