Contracting Bipartite Graphs to Paths and Cycles
Testing if a given graph G contains the k-vertex path Pk as a minor or as an induced minor is trivial for every fixed integer k ≥ 1. However, the situation changes for the problem of checking if a graph can be modified into Pk by using only edge contractions. In this case the problem is known to be NP-complete even if k = 4. This led to an intensive investigation for testing contractibility on ...
متن کاملZero Cycles on Singular Varieties and Their Desingularisations
We use pro cdh-descent of K-theory to study the relationship between the zero cycles on a singular variety X and those on its desingularisation X . We prove many cases of a conjecture of S. Bloch and V. Srinivas, and relate the Chow groups of X to the Kerz–Saito Chow group with modulus of X ′ relative to its exceptional fibre. 2010 Mathematics Subject Classification: 14C35
متن کاملReciprocal contracting
This paper models competing mechanism games as extensive games where the extensive form is incompletely understood by a modeler, typically because the modeler doesn’t see all the messages that are being exchanged and doesn’t understand all the contracts that can be enforced. For this reason, the revelation principle can’t be used to characterize supportable outcomes. The paper provides a relati...
متن کاملContracting Logics
In this paper, inspired in the field of belief revision, it is presented a novel operation for defining a new logic given a known logic. The operation consists in removing some (maybe undesirable) derived rule from a logic. Besides removing the ‘undesirable’ rule, this operation (called contraction) should change the logic in a minimal way. This paper presents formal definitions for contraction...
