Integral equation methods offer a powerful unified framework for accurate modeling in fields such as acoustics, electromagnetics, elastostatics, nano-optics, microfluidics, biophysics, and geophysics, governed by PDEs such as the Laplace, Stokes, Helmholtz, Maxwell, Navier, heat and Navier-Stokes equations. For constant-coefficient problems, they reduce the unknowns to functions defined on the boundary alone. Even for variable-coefficient and nonlinear problems, they have distinct advantages over standard finite difference and finite element methods. Aiming at graduate students, postdocs, and practitioners, we will introduce the basic mathematical foundation of such methods, illustrate their use in applications, and offer expert-run hands-on tutorials using a set of efficient software tools. These tools allow large problems to be solved with high-order accuracy in a time almost linear in the number of unknowns (so-called "fast algorithms"). The integral equation framework is geometrically flexible, allowing for input from a variety of CAD formats and the incorporation of corner and edge singularities in bounded, unbounded or periodic domains. Topics will include: integral equation formulations, discretization, fast solvers, PDEs on surfaces, volumetric representations for variable-coefficient PDEs, and applications to steady-state and time-dependent problems.

Software
Most of the software tutorials are in MATLAB. We request all attendees to have a working copy of MATLAB, preferably R2020a or greater. The softwares should also work on octave, but some features may not be available. We encourage all participants to install the following software packages before the start of the conference:
In case you run into installation issues, there will be an installation support session on June 7, 2024 via zoom between 10 am - 12 pm, and 2pm - 4pm.
