We study the probabilistic consequences of the choice of the basic number field in the quantum formalism. We demonstrate that by choosing a number field for a linear space representation of quantum model it is possible to describe various interference phenomena. We analyse interference of probabilistic alternatives induced by real, complex, hyperbolic (Clifford) and p‐adic representations. 相似文献

Noncooperative games of a finite number of persons with interval-valued payoff functions are considered. The concept of an equilibrium situation is introduced. A reduction of such games to deterministic noncooperative games is proposed. Properties of the reduced games are discussed. Interval antagonistic and bimatrix games are examined, and illustrative examples are considered. 相似文献

A group is said to be Hopfian if every surjective endomorphism of the group is injective. We show that finitely generated subgroups of torsion-free hyperbolic groups are Hopfian. Our proof generalizes a theorem of Sela (Topology
35 (2) 1999, 301–321). 相似文献

This paper continues earlier studies by Bhatia and Li on eigenvalue perturbation theory for diagonalizable matrix pencils having real spectra. A unifying framework for creating crucial perturbation equations is developed. With the help of a recent result on generalized commutators involving unitary matrices, new and much sharper bounds are obtained.

Applying real options thinking to company valuation seems theoretically and intuitively appealing. However, the real option
analogy of a single European option as well as the compound option proxy perform poorly when applied to company valuation.
We therefore suggest to rework the building blocks of real option applications to corporate valuation.
We introduce a framework to delineate the distribution of the underlying asset in the risk neutral world, which is important
in order to value any derivative. This is achieved by an algorithm to calibrate a basket option model using real world data
of observed share prices. The fitting takes account of the class of stable distributions. The index of stability of asymmetric
α stable distribution serves as an over-all parameter to characterise the specific distribution. 相似文献
