Discriminating varieties

Algebra Universalis, 1994
Abstract: "In this paper we determine those locally finite varieties that generate decidable discriminator varieties when argumented by a ternary discriminator term."

Quasi-discriminator varieties

International Journal of Algebra and Computation, 2014
We generalize the notion of discriminator variety in such a way as to capture several varieties of algebras arising mainly from fuzzy logic. After investigating the extent to which this more general concept retains the basic properties of discriminator varieties, we give both an equational and a purely algebraic characterization of quasi-discriminator ...

Smooth Stable Maps of Discriminant Varieties

Proceedings of the London Mathematical Society, 1985
In this series of papers (see also the two following reviews) we classify certain smooth stable maps and then give a number of applications of the classification. Let \(\Delta\), \(O\subset R^ k\), O denote the germ of the discriminant variety of a singularity of type \(A_ k\) at the origin 0. In Commun. Pure Appl. Math.

Imperfect Price Discrimination and Variety

The Journal of Business, 1983
In many environments a monopolist can price discriminate even though consumers can select any option offered by the firm. Though consumers seem indistinguishable to the firm, the monopolist can discriminate by exploiting its knowledge of the joint distribution of agents' characteristics (in this paper, locations and reservation prices) to offer the ...

Discriminator polynomials and arithmetical varieties

Algebra Universalis, 1985
The author proves the following theorem: Given a locally finite semisimple arithmetical variety. For each natural number n there exists a term \(t_ n(x,y,z,u_ 1,...,u_ n)\) such that in any n-generated simple algebra, with generators \(s_ 1,...,s_ n\) the polynomial \(t_ n(x,y,z,s_ 1,...,s_ n)\) is a discriminator polynomial. A corollary of this is the

Skew Boolean algebras and discriminator varieties

Algebra Universalis, 1995
The authors introduce and investigate the class of skew Boolean algebras which are also meet semilattices under the natural skew lattice partial order. The class has connections with two other classes of algebras, namely implicative BCK-algebras and algebras in discriminator varieties.

Compact algebras in discriminator varieties

Algebra Universalis, 1993
It is proved that the compact members of a discriminator variety of topological algebras are precisely the products of finite simple algebras.
