A Note on Exactness and Stability in Homotopical Algebra
Exact sequences are a well known notion in homological algebra. We investigate here the more vague properties of “homotopical exactness”, appearing for instance in the fibre or cofibre sequence of a map. Such notions of exactness can be given for very general “categories with homotopies” having homotopy kernels and cokernels, but become more interesting under suitable “stability” hypotheses, sa...
متن کاملDeducibility and Exactness
What I intend to show in this short paper is how one can translate in relational terms the concepts of deducibility and exactness which are the result of a sequence of works on homology theory and algebraic topology. As we shall see, we shall obtain as a final product the possibility to associate to an arbitrary binary relation R a difunctional relation R contained in R, in contrast with the di...
متن کاملAlgorithms for Core Stability, Core Largeness, Exactness, and Extendability of Flow Games
In this paper, we give linear time algorithms to decide core stability, core largeness, exactness, and extendability of flow games on uniform networks (all edge capacities are 1). We show that a uniform flow game has a stable core if and only if the network is a balanced DAG (for all non-terminal vertices, indegree equals outdegree), which can be decided in linear time. Then we show that unifor...
متن کاملTowards exactness in geomorphometry
Exactness of results of geomorphometric research depends not only on measurement and computational exactness but also on exact definition of measured objects and exactness of interpretation of the geomorphometric variables. The need to consider all aspects of exactness in mutual relationships is exemplified from the use of third order local point-based variables.
متن کاملSemi-abelian Categories and Exactness
We show that every semi-abelian category, as defined by Palamodov, possesses a maximal exact structure in the sense of Quillen and that the exact structure of a quasi-abelian category is a special case thereof.
