Restricted Priestley Dualities and Discriminator Varieties [PDF]
Anyone who has ever worked with a variety~$\boldsymbol{\mathscr{A}}$ of algebras with a reduct in the variety of bounded distributive lattices will know a restricted Priestley duality when they meet one---but until now there has been no abstract definition. Here we provide one.

The Subquasivariety Lattice of a Discriminator Variety
The quaterny discriminator on a set \(M\) is the mapping \(d:M^4\to M\) defined by \(d(x,y,z,w):=z\) if \(x=y\) and \(d(x,y,z,w):=w\) otherwise. A variety is called a discriminator variety if it is generated by a class \({\mathbf K}\) of algebras of the same type such that there exists a term representing the quaternary discriminator on every algebra ...

Decidable Discriminator Varieties from Unary Classes [PDF]
Let K \mathcal {K} be a class of (universal) algebras of fixed type. K t {\mathcal {K}^t} denotes the class obtained by augmenting each member of K \mathcal {K} by the ternary discriminator function (

Characterization of discriminator varieties [PDF]
The discriminator function on a set \(A\) is the function \(t:A^3\to A\) defined by \(t(a,b,c)=a\) if \(a\neq b\), and \(t(a,b,c)=c\) if \(a=b\). A ternary term \(t(x,y,z)\) is called a discriminator term for algebra \({\mathcal A}\) if it represents the discriminator function on \(A\).

Dual binary discriminator varieties
Summary: Left normal bands, strongly distributive skew lattices, implicative BCS-algebras, skew Boolean algebras, skew Boolean intersection algebras, and certain other non-commutative structures occur naturally as term reducts in the study of ternary discriminator algebras and the varieties that they generate, giving rise thereby to various classes of ...

Equationally Complete Discriminator Varieties of Groupoids [PDF]
J. Kalicki proved that there are continuum many equationally complete varieties of groupoids. In this note we give a constructive proof of this by defining a countable partial groupoid which has continuum many completions such that each completion generates an equationally complete variety, and no two distinct completions generate the same variety ...

Hybrid GAN-LSTM framework for diabetic foot ulcer image synthesis and automated diagnosis [PDF]
IntroductionThe application of artificial intelligence (AI) in the analysis of medical images faces significant challenges, chiefly due to the scarcity of well-labeled datasets that are crucial for training sophisticated diagnostic models.
