The aim of this dissertation is to use relative higher index theory to study questions of existence and classification of positive scalar curvature metrics on manifolds with boundary. First we prove a theorem relating the higher index of a manifold with boundary endowed with a Riemannian metric which is collared at the boundary and has positive scalar curvature there, to the relative higher index as defined by Chang, Weinberger and Yu. Next, we define relative higher rho-invariants associated to positive scalar curvature metrics on manifolds with boundary, which are collared at boundary. In...

Obstructions to the existence of positive scalar curvature metrics are considered. This thesis has two fairly independent parts. The first part of this thesis proves that the Roe (or coarse) index of the Dirac-Rosenberg operator vanishes in presence of a metric of uniformly positive scalar curvature outside a compact subset of an non-compact complete spin manifold. As an application of this result, Hanke-Pape-Schick's codimension two obstruction result to positive scalar curvature, which generalizes a previous result by Gromov-Lawson, is considered. The second part of this thesis provides a ...

Download Secondary Large-scale Index Theory and Positive Scalar Curvature Book in PDF, Epub and Kindle
We develop a theory of secondary invariants associated to complete Riemannian metrics of uniformly positive scalar curvature outside a prescribed subset on a spin manifold. We work in the context of large-scale (or "coarse") index theory. These invariants can be used to distinguish such Riemannian metrics up to concordance relative to the prescribed subset. We exhibit a general external product formula for partial secondary invariants, from which we deduce product formulas for the Rho-invariant of a metric with uniformly positive scalar curvature as well as for the coarse index difference o...

Download Perspectives In Scalar Curvature (In 2 Volumes) Book in PDF, Epub and Kindle
Volume I contains a long article by Misha Gromov based on his many years of involvement in this subject. It came from lectures delivered in Spring 2019 at IHES. There is some background given. Many topics in the field are presented, and many open problems are discussed. One intriguing point here is the crucial role played by two seemingly unrelated analytic means: index theory of Dirac operators and geometric measure theory.Very recently there have been some real breakthroughs in the field. Volume I has several survey articles written by people who were responsible for these results.For Volume II, many people in areas of mathematics and physics, whose work is somehow related to scalar curvature, were asked to write about this in any way they pleased. This gives rise to a wonderful collection of articles, some with very broad and historical views, others which discussed specific fascinating subjects.These two books give a rich and powerful view of one of geometry's very appealing sides.

Download Concordances in Positive Scalar Curvature and Index Theory Book in PDF, Epub and Kindle
We apply the strategy to study of diffeomorphisms via block diffeomorphisms to the world of positive scalar curvature (psc) metrics. For each closed psc manifold, we construct the cubical set of all psc block metrics, the so called concordance set, which only encodes concordance information of psc metrics within its homotopy type. We show that the concordance is a cubical Kan set, give a geometric description for the group structure of the combinatorial homotopy groups, and construct a comparison map from the cubical model of the space of psc metrics on the underlying manifold to the concor...

Download Higher Index Theory Book in PDF, Epub and Kindle
Index theory studies the solutions to differential equations on geometric spaces, their relation to the underlying geometry and topology, and applications to physics. If the space of solutions is infinite dimensional, it becomes necessary to generalise the classical Fredholm index using tools from the K-theory of operator algebras. This leads to higher index theory, a rapidly developing subject with connections to noncommutative geometry, large-scale geometry, manifold topology and geometry, and operator algebras. Aimed at geometers, topologists and operator algebraists, this book takes a friendly and concrete approach to this exciting theory, focusing on the main conjectures in the area and their applications outside of it. A well-balanced combination of detailed introductory material (with exercises), cutting-edge developments and references to the wider literature make this a valuable guide to this active area for graduate students and experts alike.
