This book brings together both new material and
recent surveys on some topics in differential equations that are
either directly relevant to, or closely associated with, mathematical
physics.

Its topics include asymptotic formulas for the ground-state energy
of fermionic gas, renormalization ideas in quantum field theory from
perturbations of the free Hamiltonian on the circle,
\(J\)-selfadjoint Dirac operators, spectral theory of
Schrödinger operators, inverse problems, isoperimetric
inequalities in quantum mechanics, Hardy inequalities, and
non-adiabatic transitions.

Excellent survey articles on Dirichlet-Neumann inverse problems on
manifolds (by Uhlmann), numerical investigations associated with Laplacian
eigenvalues on planar regions (by Trefethen), Snell's law and propagation
of singularities in the wave equation (by Vasy), and random operators on tree
graphs (by Aizenmann) make this book interesting and valuable for graduate
students, young mathematicians, and physicists alike.
