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

The purpose of Sayas Numerics Day is

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 2022 took place as an IN-PERSON ONLY MEETING

PARKING

The PARKING MAP shows that ample parking is available a very short distance from the ITE building (at G4 on the map) in zones marked A (red) and D (purple-ish). People can also park in the Commons Garage (E), or the visitor parking on top of the Commons Garage (where normally visitors pay). Parking is free on Saturday!

ACCOMMODATION

We have reserved rooms at a rate of $125. This offer may no longer be available after September 2.
