Let M be a compact manifold with a fixed spin structure χ. The Atiyah-Singer index theorem implies that for any metric g on M the dimension of the kernel of the Dirac operator is bounded from below by a topological quantity depending only on M and χ. We show that for generic metrics on M this bound is attained.
متن کاملBernd Ammann , Mattias Dahl
We associate to a compact spin manifoldM a real-valued invariant τ(M) by taking the supremum over all conformal classes of the infimum inside each conformal class of the first positive Dirac eigenvalue, when the metrics are normalized to unit volume. This invariant is a spinorial analogue of Schoen’s σ-constant, also known as the smooth Yamabe invariant. We prove that if N is obtained from M by...
متن کاملThe State of PEP ? Bernd
The PEP tool can be considered to be one of the most widely distributed Petri net based tools. A continuously increasing functionality and an adequate graphical user interface may have been good reasons for its acceptance. Currently the tool contains approximately 500,000 lines of source code, and supports (to the best of our knowledge) the widest variety of input formalisms and veriication met...
متن کاملBecker nevus syndrome.
Becker nevus syndrome is a phenotype characterized by the fundamental presence of Becker's nevus with ipsilateral hypoplasia of the breast or other skin, skeletal and/or muscular disorders. This syndrome generally originates at birth, intensifies significantly in adolescence and is one of the syndromes that constitute epidermal nevus syndrome. To the best of our knowledge, this is the first cas...
متن کاملCould Spontaneous Transitions be Spontaneous ? 1 Bernd
It is considered to re-formulate quantum theory as it appears: A theory of continuous and causal time evolution, interrupted by discontinuous and stochastic jumps. Relying on a global reduction process, a hypothesis is introduced postulating spontaneous collapse of superpositions of states which describe spontaneous absorption or emission. The collapse probability determines a mean collapse tim...
