Sticky central limit theorems on open books
Abstract
Given a probability distribution on an open book (a metric space obtained by gluing
a disjoint union of copies of a half-space along their boundary hyperplanes), we define
a precise concept of when the Fréchet mean (barycenter) is sticky. This nonclassical
phenomenon is quantified by a law of large numbers (LLN) stating that the empirical
mean eventually almost surely lies on the (codimension 1 and hence measure 0) spine
that is the glued hyperplane, and a central limit theorem (CLT) stating that the limiting
distribution is Gaussian and supported on the spine.We also state versions of the
LLN and CLT for the cases where the mean is nonsticky (i.e., not lying on the spine)
and partly sticky (i.e., is, on the spine but not sticky). © Institute of Mathematical

Professor of Mathematics
Professor Miller's research centers around problems in geometry, algebra, topology,
combinatorics, statistics, probability, and computation originating in mathematics
and the sciences, including biology, chemistry, computer science, and imaging.The
techniques range, for example, from abstract algebraic geometry or commutative algebra
of ideals and varieties to concrete metric or discrete geometry of polyhedral spaces;
from deep topological constructions such as equivariant K-theory a
James H. Nolen
Associate Professor of Mathematics
I study partial differential equations and probability, which have been used to model
many phenomena in the natural sciences and engineering. In some cases, the parameters
for a partial differential equation are known only approximately, or they may have
fluctuations that are best described statistically. So, I am especially interested
in differential equations modeling random phenomena and whether one can describe the
statistical properties of solutions to these equations. Asymptotic anal
