Children’s emerging ability to discriminate L1-varieties

First Language, 2018
Children in Austria are exposed to a large amount of variation within the German language. Most children grow up with a local dialect, German standard language and ‘intermediate’ varieties summarized as ‘Umgangssprache’. Using an ABX design, this study analyses when Austrian children are able to discriminate native varieties of their L1 German ...

Decidable discriminator varieties with lattice stalks

Algebra Universalis, 1994
Abstract: "We determine those universal classes of lattices which generate a decidable discriminator variety when augmented by a ternary discriminator term. They are the locally finite universal classes whose finite members are almost homogeneous."

Discriminant loci of varieties with smooth normalization

Communications in Algebra, 2000
Let X be a smooth complex projective n-fold endowed with an ample and spanned line bundle (L). Under the assumption that Γ(L) defines a generically one-to-one map we describe the singular set of the general element in the main component of the discriminant locus of |L|. This description is used to show that (X:,L) is covered by linear Pk’s, where k + 1

Iterated discriminator varieties have undecidable theories

Algebra Universalis, 1985
The author establishes a fairly wide class of discriminator varieties with undecidable theories. The result generalizes the most important example, namely, the variety \(CA_ 1\) of monadic algebras.

Countable embeddability skeletons of discriminator varieties

Algebra and Logic, 1989
Let \({\mathbb{V}}\) be a variety of algebras. The set I\({\mathbb{V}}\) of isomorphism types of \({\mathbb{V}}\)-algebras together with the quasi-order \(\leq\) defined by the condition \(a\leq b\) iff any algebra of isomorphism type a can be embedded into some algebra of isomorphism type b, is called the embeddability skeleton of \({\mathbb{V ...

Vine variety discrimination with airborne imaging spectroscopy

SPIE Proceedings, 2007
We aim at the discrimination of varieties within a single plant species (Vitis vinifera) by means of airborne hyperspectral imagery collected using a CASI-2 sensor and supervised classification, both under constant and varying within-scene illumination conditions.

Projective Dual Varieties and General Discriminants

1994
We denote by P n the standard complex projective space of dimension n. Thus a point of P n is given by (n + 1) homogeneous coordinates (x 0:...: x n ), x i ∈ C, which are not all equal to 0 and are regarded modulo simultaneous multiplication by a non-zero number.

Expansions of Semi-Heyting Algebras I: Discriminator Varieties

Studia Logica, 2011
This paper is a contribution toward developing a theory of expansions of semi-Heyting algebras. The paper has the following objectives:{\parindent=6mm \begin{itemize}\item[(1)] To prove the validity of the following conjecture: There exists a variety \textbf{V} of algebras which would provide a unifying framework to state and prove results which would ...
