The international conference "Perturbations, Asymptotics, and related Tools (PAT)" will bring together many experts working on the topics of perturbation and asymptotic problems for elliptic differential equations, and on more abstract and foundational questions that are essential to deal with perturbations and asymptotics. Said topics will include (but are not restricted to): perturbations of the domain and/or of the underlying geometric structure; corner singularities and their effects on solutions of BVP; perturbations of the mass and of other parameters; regularity properties of layer potentials and their numerical computations; degenerate, Steklov, nonlinear, and higher order problems.

The main goal of the conference will be to provide a common place for specialists coming from different backgrounds while working on similar problems to discuss together exchanging ideas and techniques, to stimulate new collaborations, as well as to present new challenging problems and open questions.

Participation is open to all mathematicians and scientists interested in the topics of perturbations and asymptotics for differential equations and related problems and tools.
