Decomposable extensions of difference fields

نویسنده

چکیده

We define the decomposable extensions of difference fields and study the irreducibility of q-Painlevé equation of type A 7 ′ . Every strongly normal extension or Liouville-Franke extension, the latter of which is a difference analogue of the Liouvillian extension, satisfies that its appropriate algebraic closure is a decomposable extension.

Polynomially Decomposable Global Cost Functions in Weighted Constraint Satisfaction

In maintaining consistencies, such as GAC*, FDGAC* and weak EDGAC*, for global cost functions, Weighted CSP (WCSP) solvers rely on the projection and extension operations, which entail the computation of the cost functions’ minima. Tractability of this minimum computation is essential for efficient execution. Since projections/extensions modify the cost functions, an important issue is tractabl...

Constructing vertex decomposable graphs

‎Recently‎, ‎some techniques such as adding whiskers and attaching graphs to vertices of a given graph‎, ‎have been proposed for constructing a new vertex decomposable graph‎. ‎In this paper‎, ‎we present a new method for constructing vertex decomposable graphs‎. ‎Then we use this construction to generalize the result due to Cook and Nagel‎.

Logical Analysis of Data with Decomposable Structures

In such areas as knowledge discovery, data mining and logical analysis of data, methodologies to 0nd relations among attributes are considered important. In this paper, given a data set (T; F) where T ⊆ {0; 1}n denotes a set of positive examples and F ⊆ {0; 1}n denotes a set of negative examples, we propose a method to identify decomposable structures among the attributes of the data. We 0rst s...

Bargaining with nonanonymous disagreement: Decomposable rules

We analyze bargaining situations where the agents’ payoffs from disagreement depend on who among them breaks down the negotiations. We model such problems as a superset of the standard domain of Nash (1950). We first show that this domain extension creates a very large number of new rules. Particularly, decomposable rules (which are extensions of rules from the Nash domain) constitute a nowhere...
