Generalizations of Approximable Concept Lattice

چکیده
B. Ganter, R. Wille initiated formal concept analysis, concept lattice is one of the main notions and tools, see [12]. Some researchers have investigated the fuzzification of the classical crisp concept lattice. In [1], from the point of view of fuzzy logic, R. Bĕlohlávek investigated concept lattice in fuzzy setting. In [16, 17], S. Krajči studied generalized concept lattice. On the other hand, as a generalization of concept, in [15, 21, 22], Zhang, P. Hitzler, Shen defined the notion of approximable concept on a Chu space. In this paper, we introduce two generalizations of approximable concept lattice: approximable concept lattice in the sense of R. Bĕlohlávek, and generalized approximable concept in the sense of S. Krajči.

The Geometry of Badly Approximable Vectors
A vector v = (v1, v2, . . . , vk) in R k is -badly approximable if for all m, and for 1 ≤ j ≤ k, the distance ‖mvj‖ from mvj to the nearest integer satisfies ‖mvj‖ > m−1/k. A badly approximable vector is a vector that is -badly approximable for some > 0. For the case of k = 1, these are just the badly approximable numbers, that is, the ones with a continued fraction expansion for which the part...
متن کاملA Categorical View on Algebraic Lattices in Formal Concept Analysis
Formal concept analysis has grown from a new branch of the mathematical field of lattice theory to a widely recognized tool in Computer Science and elsewhere. In order to fully benefit from this theory, we believe that it can be enriched with notions such as approximation by computation or representability. The latter are commonly studied in denotational semantics and domain theory and captured...
متن کاملFlows on Homogeneous Spaces and Diophantine Properties of Matrices
We generalize the notions of badly approximable (resp. singular) systems of m linear forms in n variables, and relate these generalizations to certain bounded (resp. divergent) trajectories in the space of lattices in Rm+n.
متن کاملA Cartesian Closed Category of Approximable Concept Structures
Infinite contexts and their corresponding lattices are of theoretical and practical interest since they may offer connections with and insights from other mathematical structures which are normally not restricted to the finite cases. In this paper we establish a systematic connection between formal concept analysis and domain theory as a categorical equivalence, enriching the link between the t...
متن کاملMulti-adjoint t-concept lattices
The t-concept lattice is introduced as a set of triples associated to graded tabular information interpreted in a non-commutative fuzzy logic. Following the general techniques of formal concept analysis, and based on the works by Georgescu and Popescu, given a non-commutative conjunctor it is possible to provide generalizations of the mappings for the intension and the extension in two differen...
