The use of futures prices to predict commodity cash prices is important both to practitioners and researchers yet the literature provides conflicting results on the ability of futures prices to predict cash prices. Brenner and Kroner [Journal of Financial and Quantitative Analysis 30 (1995) 23]...

In this paper we show how geometric problems defined by constraints with interval parameters can be solved by combining a symbolic geometric constraint solving phase and a numerical evaluation phase based on interval analysis techniques

A state-space formula of the decentralized Bezout identity for a singular decentralized control plant is developed, which provides a useful tool for investigating singular decentralized control problems with the stable fractional approach

The performance sensitivity of linear systems, with stable feedback perturbations both on the plant and the feedback controller, is discussed. Using – norm, the sufficient condition for the robust stability is derived. Also, the upper bounds for the sensitivity function matrix and the...

Estimates from below of the number of solutions to boundary value problems of the type , are given for certain classes of continuous functions provided that there exists at least one solution ξ() to the BVP under consideration. The number of solutions depends on oscillatory properties of a...

The horizontal advection is one of the most important physical processes in an air pollution model. While it is clear how to describe mathematically this process, the computer treatment of the arising first-order partial differential equation (PDE) causes great difficulties. It is assumed that...

A probabilistic rationale for -divergence minimization (relative entropy maximization), non-parametric likelihood maximization and -divergence minimization (Jeffreys' entropy maximization) criteria is provided

Apart from the regular and adjugate compounds of a matrix, an inverse compound of a matrix is defined. Theorems of Laplace, Binet-Cauchy, and Jacobi are given in terms of these compounds. Compound matrices allow the statements of the theorems to be terse and precise

Let ≥ 2, = 2 + 1, and let , …, each be a multiple of . The graph × … × consists of isomorphic connected components, each of which is ( – 1)-regular and admits of a vertex partition into smallest independent dominating sets. Accordingly, (independent) domination number of each connected...
