This paper surveys experimental literature relating to mergers. We put particular emphasis on discussing whether this literature addresses the issues that are relevant for competition policy. We also include some suggestions as to how the fit between the experiments and the requirements of competition policy research might be improved. ––––––––––––––––––––– Affiliations: *Lorenz Götte, Institut...

We give explicit constructions of certain majorizing measures.These constructions allow us to give a unified proof of deep matching theo-rems of Ajtai, Komlbs, and Tusnady, of Leighton and Shor, and of Shor, aswell as of more precise and more general results in a similar spirit.

Decision trees have been well studied and widely used in knowledge discovery and decision support systems. Although the problem of finding an optimal decision tree has received attention, it is a hard optimization problem. Here we propose utilizing a genetic algorithm to improve on the finding of ap-propriate decision trees. We present a method to encode/decode a decision tree to/from a chromo-...

Using a recently developed technique (SEA TADPOLE) for easily measuring the complete spatiotemporal electric field of light pulses with micrometer spatial and femtosecond temporal resolution, we directly demonstrate the formation of theo-called boundary diffraction wave and Arago's spot after an aperture, as well as the superluminal propagation of the spot. Our spatiotemporally resolved measure...

We prove dimension formulas for the cotangent spaces T 1 and T 2 for a class of rational surface singularities by calculating a correction term in the general dimension formulas. We get that it is zero if the dual graph of the rational surface singularity X does not contain a particular type of configurations, and this generalizes a result of Theo de Jong stating that the correction term c(X) i...

irrefragable pathological proof in its support. If it is inflammatory oedema, then it is not enlargement of the head and neck of the humerus ; and if it is bony enlargement, then it is cancerous and will not disappear after operation. But hear what he says in the next sentence:?"It would seem to be the first manifestations of that implication of the osseous system which becomes so painfully evi...

One of the landmarks in approximation algorithms is theO( √ logn)-approximation algorithm for theUniform Sparsest Cut problem by Arora, Rao and Vazirani from 2004. The algorithm is based on a semidefinite program that finds an embedding of the nodes respecting the triangle inequality. Their core argument shows that a randomhyperplane approachwill find two large sets ofΘ(n)many nodes each that h...
