Tail and free poset algebras. [PDF]
, 2004 We characterize free poset algebras F(P) over partially ordered sets and show that they can be represented by upper semi-lattice algebras. Hence, the uniqueness, in decomposition into normal form, using symmetric difference, of non-zero elements of F(P ...

Hyperfinite and standard unifications for physical theories
International Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 2, Page 93-102, 2001., 2001 A set of physical theories is represented by a nonempty subset {SNjV|j∈ℕ} of the lattice of consequence operators defined on a language Λ. It is established that there exists a unifying injection 𝒮 defined on the nonempty set of significant representations for natural systems M ⊂ Λ. If W ∈ M, then 𝒮W is a hyperfinite ultralogic and ⋃{SNjV(W)|j∈ℕ}=𝒮W(*W)

(In)Security of Ring-LWE Under Partial Key Exposure
Journal of Mathematical Cryptology, 2020 We initiate the study of partial key exposure in Ring-LWE (RLWE)-based cryptosystems. Specifically, we (1) Introduce the search and decision Leaky R-LWE assumptions (Leaky R-SLWE, Leaky R-DLWE), to formalize the hardness of search/decision RLWE under ...

, 2016 In a paper published in 2012, the second author extended the well-known fact that Boolean algebras can be defined using only implication and a constant, to De Morgan algebras-this result led him to introduce, and investigate (in the same paper), the ...

Fantastic filters of lattice implication algebras
International Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 4, Page 277-281, 2000., 2000 The notion of a fantastic filter in a lattice implication algebra is introduced, and the relations among filter, positive implicative filter, and fantastic filter are given. We investigate an equivalent condition for a filter to be fantastic, and state an extension property for fantastic filter.

Rough sets based on fuzzy ideals in distributive lattices
Open Mathematics, 2020 In this paper, we present a rough set model based on fuzzy ideals of distributive lattices. In fact, we consider a distributive lattice as a universal set and we apply the concept of a fuzzy ideal for definitions of the lower and upper approximations in ...

Braid groups of imprimitive complex reflection groups [PDF]
, 2015 We obtain new presentations for the imprimitive complex reflection groups of type $(de,e,r)$ and their braid groups $B(de,e,r)$ for $d,r \ge 2$. Diagrams for these presentations are proposed.

ON P-SEMISIMPLE IN KK-ALGEBRAS
, 2015 In the present paper, we introduce the notion of p-semisimple in KK-algebras and investigate some related properties. We also give some necessary and sufficient conditions under which a branchwise commutative KKalgebra is also commutative.

Synchronization and information transmission in networks [PDF]
, 2014 The amount of information produced by a network may be measured by the mutual information rate. This measure, the Kolmogorov-Sinai entropy and the synchronization interval are expressed in terms of the transversal Lyapunov exponents. Thus, these concepts
