13. A class of strict local martingales

Herdegen, Martin P.G. and Herrmann, Sebastian (2014)

Many results in stochastic analysis and mathematical finance involve local martingales. However, specific examples of strict local martingales are rare and analytically often rather unhandy. We study local martingales that follow a given deterministic function up to a random time...

18. A Comprehensive Operational Semantics of the SCOOP Programming Model

Morandi, Benjamin, Nanz, Sebastian and Meyer, Bertrand (2012)

Operational semantics has established itself as a flexible but rigorous means to describe the meaning of programming languages. Oftentimes, it is felt necessary to keep a semantics small, for example to facilitate its use for model checking by avoiding state space explosion....

19. A convergence result for the Emery topology and a variant of the proof of the fundamental theorem of asset pricing

Cuchiero, Christa and Teichmann, Josef (2014)

We show that No unbounded profit with bounded risk (NUPBR) implies predictable uniform tightness (P-UT), a boundedness property in the Emery topology which has been introduced by C. Stricker [32]. Combining this insight with well known results from J. M´emin and L. S lominski [26]...

20. Acting autonomously of mimicking the state and peers?

Dreher, Axel, Nunnenkamp, Peter, Öhler, Hannes and Weisser, Johannes (2009)

NGO aid is still widely believed to be superior to official aid (ODA). However, the incentives of NGOs to excel and target aid to the poor and deserving are increasingly disputed. We contribute to the emerging literature on the allocation of NGO aid by performing panel Tobit...

21. Active spanning trees and SLE

Kassel, Adrien and Wilson, David B. (2015)

We consider the Peano curve separating a spanning tree from its dual spanning tree on an embedded planar graph, where the tree and dual tree are weighted by y to the number of active edges, and "active" is in the sense of the Tutte polynomial. When the graph is a portion of the...

23. Activists versus Captured Regulators

Daubanes, Julien and Rochet, Jean-Charles (2013)

We analyze the consequences of activism in a regulated industry where the regulator has been captured by the industry. Unlike ordinary economic agents, activists are insensitive to monetary incentives. Moreover, they are less well informed than regulators and their actions generate...

26. Activity spaces, biographies, social networks and their welfare gains and externalities: Some hypotheses and empirical results

Axhausen, Kay W. (2005)

The repeated interactions and exchanges in formal and informal networks, e.g. family, firms, associations, friendship circles, regulars of a bar, are central to our daily life. There is no reason to assume, that the geography of the members of the networks, to which one belongs,...

27. Adaptive Lasso for High Dimensional Regression and Gaussian Graphical Modeling

Zhou, Shuheng, van de Geer, Sara and Bühlmann, Peter (2009)

We show that the two-stage adaptive Lasso procedure (Zou, 2006) is consistent for high-dimensional model selection in linear and Gaussian graphical models. Our conditions for consistency cover more general situations than those accomplished in previous work: we prove that...

28. Adaptive Submodular Optimization under Matroid Constraints

Golovin, Daniel and Krause, Andreas (2011)

Many important problems in discrete optimization require maximization of a monotonic submodular function subject to matroid constraints. For these problems, a simple greedy algorithm is guaranteed to obtain near-optimal solutions. In this article, we extend this classic result to a...

43. A Gap Theorem for Willmore Tori and an application to the Willmore Flow

Mondino, Andrea and Nguyen, Huy The (2013)

In 1965 Willmore conjectured that the integral of the square of the mean curvature of a torus immersed in $R^3$ is at least $2\pi^2$ and attains this minimal value if and only if the torus is a M\ "obius transform of the Clifford torus. This was recently proved by Marques and...
