Riemanniageometry is characterized, and research is oriented towards and shaped by concepts (geodesics, connections, curvature, ...) and objectives, iparticular to understand certaiclasses of (pact) Riemanniamanifolds defined by curvature conditions (constant or positive or curvature, ...). By way of contrast, geometric analysis is a perhaps somewhat less systematic collectioof techniques, for solving extremal problems naturally arising igeometry and for investigating and characterizing their solutions. It turns out that the two fields plement each other very well; geometric analysis offers tools for solving difficult problems igeometry, and Riemanniageometry stimulates progress igeometric analysiy setting ambitious goals. It is the aim of thiook to be a systematic and prehensive introductioto Riemanniageometry and a representative introductioto the methods of geometric analysis. It attempts a synthesis of geometric and analytic methods ithe study of Riemanniamanifolds. The present work is the s
