Comparison and rigidity results on compact Riemannian manifolds with boundary
Montag, 9.4.18, 16:00-17:00, Raum 125, Ernst-Zermelo-Str. 1
For compact Riemannian manifolds with nonempty boundary, it is\ninteresting to study the relationship between the geometry on the\nboundary and geometry of the interior. I will discuss comparison and\nrigidity results for manifolds with a lower bound for the Ricci\ncurvature. The focus will be on sharp geometric inequalities that yield\nrigidity results in the equality case.\n\nIf time allows I will also discuss results for manifolds with a lower\nbound for the scalar curvature. Many results and questions in this\ndirection are motivated by general relativity.

Motivationsentwicklung im Mathematikstudium
Donnerstag, 26.4.18, 17:00-18:00, Hörsaal II, Albertstr. 23b
Der Übergang in ein Mathematikstudium wird oft problematisch erlebt.\nViele Studierende verlieren schnell ihre ursprünglich hohe intrinsische\nMotivation, ein hoher Anteil verlässt den Studiengang schon im ersten\nJahr wieder. Der Vortrag betrachtet diese Motivationsproblematik aus der\nPerspektive der Interesse-Forschung und der Selbstbestimmungstheorie der\nMotivation. In einer qualitativen Studie wurden 21 Studierende bis zu\ndrei Mal im ersten Studienjahr zu ihrem Studienerleben interviewt. Die\nAussagen erlauben eine genauere Beschreibung der Interessenentwicklung\nund des Erlebens der psychologischen Grundbedürfnisse. Die Ergebnisse\nzeigen vielfältige Gründe der Motivationsproblematik, insbesondere\nerklärt sich problematisches Autonomieerleben durch Schwierigkeiten der\nStudierenden mit dem selbstgesteuerten Arbeiten. Weiter werden\nVerbindungen zu den Besonderheiten der Hochschulmathematik und dem\nUnterschied zwischen Fach- und Gymnasiallehramtsstudierenden sichtbar.\n\n

Consistency of stepwise uncertainty reduction strategies for Gaussian processes
Freitag, 27.4.18, 12:00-13:00, Raum 404, Ernst-Zermelo-Str. 1
In the first part of the talk, we will introduce spatial Gaussian processes.\nSpatial Gaussian processes are widely studied from a statistical point of view, and have found applications in many fields, including geostatistics, climate science and computer experiments. Exact inference can be conducted for Gaussian processes, thanks to the Gaussian conditioning theorem. Furthermore, covariance parameters can be estimated, for instance by Maximum Likelihood.\nIn the second part of the talk, we will introduce a class of iterative sampling strategies for Gaussian processes, called 'stepwise uncertainty reduction' (SUR). We will give examples of SUR strategies which are widely applied to computer experiments, for instance for optimization or detection of failure domains. We will provide a general consistency result for SUR strategies, together with applications to the most standard examples.
