The aim of this article is to link Schubert varieties in the flag manifold with hyperplane arrangements. For a permutation, we construct a certain graphical hyperplane arrangement....
In this paper we produce a finite algebra which generates a variety with a PSPACE-complete membership problem. We produce another finite algebra with a γ function that grows exp...
It is widely believed that quadratic coefficients cannot be estimated from eight data in cubical array. This paper illustrates the estimation of those coefficients by means of by ...
The standard method of generating countable ordinals from uncountable ordinals can be replaced by a use of fixed point extractors available in the term calculus of Howard's s...
The existence and utilization of an internal representation of the controlled object is one of the most important features of the functioning of neural motor control systems. This ...
