Solving algebraic equations in terms of A-hypergeometric series
The roots of the general equation of degree n satisfy an A-hypergeometric system of diierential equations in the sense of Gel'fand, Kapranov and Zelevinsky. We construct the n distinct A-hypergeometric series solutions for each of the 2 n?1 triangulations of the Newton segment. This works over any eld whose characteristic is relatively prime to the lengths of the segments in the triangulation. ...
متن کاملEvolution of Algebraic Terms 1: Term to Term Operation Continuity
This study was inspired by recent successful applications of evolutionary computation to the problem of finding terms to represent arbitrarily given operations on a primal groupoid. Evolution requires that small changes in a term result in small changes in the associated term operation. We prove a theorem giving two readily testable conditions under which a groupoid must have this continuity pr...
متن کاملAn Algebraic Approach for Specifying Compound Terms in Faceted Taxonomies
A faceted taxonomy is a set of taxonomies, each describing a given domain from a different aspect, or facet. The indexing of domain objects is done through conjunctive combinations of terms from the facets, called compound terms. A faceted taxonomy has several advantages over a single hierarchy of terms, including conceptual clarity, compactness and scalability. A drawback, however, is the cost...
متن کاملCanonical Stability in Terms of Singularity Index for Algebraic Threefolds
Throughout the ground field is always supposed to be algebraically closed of characteristic zero. Let X be a smooth projective threefold of general type, denote by φm the m-canonical map of X which is nothing but the rational map naturally associated with the complete linear system |mKX |. Since, once given such a 3-fold X , φm is birational whenever m ≫ 0, thus a quite interesting thing is to ...
متن کاملInitial Algebras of Terms with Binding and Algebraic Structure
One of the many results which makes Joachim Lambek famous is: an initial algebra of an endofunctor is an isomorphism. This fixed point result is often referred to as “Lambek’s Lemma”. In this paper, we illustrate the power of initiality by exploiting it in categories of algebra-valued presheaves EM(T ), for a monad T on Sets. The use of presheaves to obtain certain calculi of expressions (with ...
