This book highlights the latest developments in the geometry of
measurable sets, presenting them in simple, straightforward terms. It
addresses nonlocal notions of perimeter and curvature and studies in
detail the minimal surfaces associated with them.
These notions of nonlocal perimeter and curvature are defined on the
basis of a non-singular kernel. Further, when the kernel is
appropriately rescaled, they converge toward the classical perimeter and
curvature as the rescaling parameter tends to zero. In this way, the
usual notions can be recovered by using the nonlocal ones. In addition,
nonlocal heat content is studied and an asymptotic expansion is
obtained.
Given its scope, the book is intended for undergraduate and graduate
students, as well as senior researchers interested in analysis and/or
geometry.
