401-5004-17LSelf-Organized Dynamics: From Emerging Consensus to Hydrodynamic FlockingW0 KP2VE. Tadmor
KurzbeschreibungNachdiplom lecture
Lernziel
InhaltWe study the dynamics of systems driven by the 'social engagement' of agents with their neighbors. Prototype models are found in opinion dynamics, flocking, self-organization of biological organisms and rendezvous of mobile systems.
Two natural questions arise in this context, namely, what is the large time behavior of such systems, and what is the effective dynamics for large crowds of agents.
The underlying issue of the first question is how different rules of engagement influence the formation of clusters, and in particular, the emergence of 'consensus'. Different paradigms of engagement yield different patterns. The tendency 'to move ahead' leads to the emergence of leaders, and 'to move around' may lead to synchronization. Different descriptions of collective dynamics arise in the context of the second question when the number of agents tends to infinity, with the formation of Dirac masses at the kinetic level of description, and critical thresholds at the level of flocking hydrodynamics.
In recent years there has been extensive activity in analyzing the self-organization of these systems. We will discuss recent developments and present open problems.
401-5006-17LTopics in Scalar CurvatureW0 KP1VR. Schoen
KurzbeschreibungNachdiplom lecture
Lernziel
InhaltThe scalar curvature plays an important role in geometry and physics. Understanding the geometry of manifolds of positive scalar curvature is intimately connected with understanding gravitational mass in general relativity. There are two general methods to deal with such problems, the Dirac operator and the theory of minimal hypersurfaces. A third method, inverse mean curvature flow, has been used effectively in three dimensions. This lecture series will focus mainly on the minimal hypersurface approach and will discuss attempts at local characterizations of manifolds of positive scalar curvature (which are related to quasilocal mass). We will then discuss approaches to proving theorems in the presence of minimal hypersurface singularities which can occur in dimension greater than seven.

401-4788-16LMathematics of (Super-Resolution) Biomedical ImagingW8 KP4GH. Ammari
KurzbeschreibungThe aim of this course is to review different methods used to address challenging problems in biomedical imaging. The emphasis will be on scale separation techniques, hybrid imaging, spectroscopic techniques, and nanoparticle imaging. These approaches allow one to overcome the ill-posedness character of imaging reconstruction in biomedical applications and to achieve super-resolution imaging.
LernzielSuper-resolution imaging is a collective name for a number of emerging techniques that achieve resolution below the conventional resolution limit, defined as the minimum distance that two point-source objects have to be in order to distinguish the two sources from each other.

In this course we describe recent advances in scale separation techniques, spectroscopic approaches, multi-wave imaging, and nanoparticle imaging. The objective is fivefold:
(i) To provide asymptotic expansions for both internal and boundary perturbations that are due to the presence
of small anomalies;
(ii) To apply those asymptotic formulas for the purpose of identifying the material parameters and certain geometric features of the anomalies;
(iii) To design efficient inversion algorithms in multi-wave modalities;
(iv) to develop inversion techniques using multi-frequency measurements;
(v) to develop a mathematical and numerical framework for nanoparticle imaging.

In this course we shall consider both analytical and computational
matters in biomedical imaging. The issues we consider lead to the investigation of fundamental problems in various branches of mathematics. These include asymptotic analysis, inverse problems, mathematical imaging, optimal control, stochastic modelling, and analysis of physical phenomena. On the other hand, deriving mathematical foundations, and new and efficient computational frameworks and tools in biomedical imaging, requires a deep understanding of the different scales in the physical models, an accurate mathematical modelling of the imaging techniques, and fine analysis of complex physical phenomena.

An emphasis is put on mathematically analyzing acoustic-electric imaging, thermo-elastic imaging, Lorentz force based imaging, elastography, multifrequency electrical impedance tomography, and plasmonic resonant nanoparticles.
401-4632-15LCausalityW4 KP2GM. H. Maathuis
KurzbeschreibungIn statistics, we are used to search for the best predictors of some random variable. In many situations, however, we are interested in predicting a system's behavior under manipulations. For such an analysis, we require knowledge about the underlying causal structure of the system.

LernzielAfter this course, you should be able to
- understand the language and concepts of causal inference
- know the assumptions under which one can infer causal relations from observational and/or interventional data
- describe and apply different methods for causal structure learning
- given data and a causal structure, derive causal effects and predictions of interventional experiments

401-3917-00LStochastic Loss Reserving MethodsW4 KP2VR. Dahms
KurzbeschreibungLoss Reserving is one of the central topics in non-life insurance. Mathematicians and actuaries need to estimate adequate reserves for liabilities caused by claims. These claims reserves have influence all financial statements, future premiums and solvency margins. We present the stochastics behind various methods that are used in practice to calculate those loss reserves.
LernzielOur goal is to present the stochastics behind various methods that are used in prctice to estimate claim reserves. These methods enable us to set adequate reserves for liabilities caused by claims and to determine prediction errors of these predictions.
InhaltWe will present the following stochastic claims reserving methods/models:
- Stochastic Chain-Ladder Method
- Bayesian Methods, Bornhuetter-Ferguson Method, Credibility Methods
- Distributional Models
- Linear Stochastic Reserving Models, with and without inflation
- Bootstrap Methods
- Claims Development Result (solvency view)
- Coupling of portfolios

401-4920-00LMarket-Consistent Actuarial Valuation
Findet dieses Semester nicht statt.
W4 KP2VM. V. Wüthrich
KurzbeschreibungIntroduction to market-consistent actuarial valuation.
Topics: Stochastic discounting, full balance sheet approach, valuation portfolio in life and non-life insurance, technical and financial risks, risk management for insurance companies.
LernzielGoal is to give the basic mathematical tools for describing insurance products within a financial market and economic environment and provide the basics of solvency considerations.
InhaltIn this lecture we give a full balance sheet approach to the task of actuarial valuation of an insurance company. Therefore we introduce a multidimensional valuation portfolio (VaPo) on the liability side of the balance sheet. The basis of this multidimensional VaPo is a set of financial instruments. This approach makes the liability side of the balance sheet directly comparable to its asset side.

The lecture is based on four sections:
1) Stochastic discounting
2) Construction of a multidimensional Valuation Portfolio for life insurance products (with guarantees)
3) Construction of a multidimensional Valuation Portfolio for a run-off portfolio of a non-life insurance company
4) Measuring financial risks in a full balance sheet approach (ALM risks)
