Mappings Associated with Vertex Triangles
Methods of linear algebra are applied to triangle geometry. The vertex triangle of distinct circumcevian triangles is proved to be perspective to the reference triangle ABC, and similar results hold for three other classes of vertex triangles. Homogeneous coordinates of the perspectors define four mappings Mi on pairs of points (U, X). Many triangles homothetic to ABC are examined, and properti...
متن کاملReasoning about Ontology Mappings
The use of logic-based representations in distributed environments such as the semantic web has lead to work on the representation of and reasoning with mappings between distributed ontologies. Up to now the investigation of reasoning methods in this area was restricted to the use of mapping for query answering or subsumption reasoning. In this paper, we investigate the task of reasoning about ...
متن کاملSome combinatorial questions about polynomial mappings
The purpose of this note is to show how recent progress in non-commutative combinatorial algebra gives a new input to Jacobian-related problems in a commutative situation. @ 1997 Elscvier Science B.V. 1991 Math. Subj. Class.: 13B2.5, 13810, 14A05
متن کاملOn a conjecture about monomial Hénon mappings
A monomial Hénon mapping is defined as the wellknown two-dimensional Hénon map with the quadratic term replaced by a monomial. This paper introduces a conjecture about monomial Hénon mappings: Even Hénon mappings are chaotic and odd Hénon mappings are not chaotic in the first quadrant of the bifurcation parameter space. This conjecture is based on numerical simulations of this type of map.
متن کاملAbout vertex-critical non-bicolorable hypergraphs
Claude BERGE C.N.R.S., Paris The hypergraphs whose chromatic number is ~ 2 ("bicolorable" hypergraphs) were introduced by E.W. Miller [13] under the name of "set-systems with Property B". This concept appears in Number Theory (see [5], [10]). It is also useful for some problems in positional games and Operations Research (see [3], [4], [7]); different results have been found under the form of i...
