SAYAS NUMERICS DAY 05/09/2026 (formerly Delmar Numerics Day) - Annual Workshop on Computational Mathematics

This is an annual meeting on research in computational mathematics in Maryland, DC, Delaware, Virginia and vicinity organized by

University of Maryland, College Park
University of Maryland, Baltimore County
George Mason University
University of Delaware

The purpose of Sayas Numerics Day is

to connect researchers of computational mathematics in VA, MD, DC, DE and adjacent areas
to provide opportunities to students, postdocs and other early career researchers

Sayas Numerics Day is named in honor of Francisco Javier Sayas (1968-2019). In addition to his many other achievements, he played a key role in establishing and running DelMar Numerics Day, and was dedicated to its mission of giving especially younger mathematicians an opportunity to share their work.

Presentation honoring Francisco Javier Sayas, given by R. Nochetto at DelMar Numerics Day 2019.

SAYAS NUMERICS DAY 2026 is an IN-PERSON ONLY MEETING

on Saturday, May 9, 2026, 9:30am-5:50pm
University of Maryland, College Park
Colloquium Room of the Math Department (MTH3206 in Kirwan Hall)
Keynote talk: Youssef Marzouk (MIT), Dynamic measure transport for sampling and quantization
14 contributed talks (20 minutes each, including questions), selected by the scientific committee.
We particularly encourage graduate students and early career researchers to attend and give talks.

The meeting is sponsored by the BRIN MATHEMATICS RESEARCH CENTER
