Improved hadronic measurements and spectral sums on the lattice [PDF]
In this thesis we address several topics of lattice QCD. As a first project we perform calculations of ground and excited states of light mesons. Especially the extraction of the excited states turns out be very difficult.

Kernels of Residuated Maps as Complete Congruences in Lattices
In a context of lattice-valued functions (also called lattice-valued fuzzy sets), where the codomain is a complete lattice L, an equivalence relation defined on L by the equality of related cuts is investigated.

Multiscale expansion and integrability properties of the lattice potential KdV equation [PDF]
We apply the discrete multiscale expansion to the Lax pair and to the first few symmetries of the lattice potential Korteweg-de Vries equation. From these calculations we show that, like the lowest order secularity conditions give a nonlinear Schrödinger

“Complete-simple” distributive lattices [PDF]
It is well known that the only simple distributive lattice is the two-element chain. We can generalize the concept of a simple lattice to complete lattices as follows: a complete lattice is complete-simple if it has only the two trivial complete congruences.

Tensor-based trapdoors for CVP and their application to public key cryptography [PDF]
We propose two trapdoors for the Closest-Vector-Problem in lattices (CVP) related to the lattice tensor product.

A complete axiomatisation of logic of lattice effect algebras [PDF]
In a recent work Foulis and Pulmannová (Stud. Logica. 100(6), 1291–1315, 2012) studied the logical connectives in lattice effect algebras. In this paper we extend their study and investigate further the logical calculus for which the lattice effect ...

Quotients and subalgebras of sup-algebras; pp. 311–322 [PDF]
An ordered algebra is called a sup-algebra if its underlying poset is a complete lattice and its operations are compatible with joins in each variable. In this article we study quotients and subalgebras of sup-algebras.

On a complete lattice of retracts of a free monoid generated by three elements [PDF]
We prove that the family of retracts of a free monoid generated by three elements, partially ordered with respect to the inclusion, is a complete lattice.

Lattice of compactifications of a topological group [PDF]
We show that the lattice of compactifications of a topological group $G$ is a complete lattice which is isomorphic to the lattice of all closed normal subgroups of the Bohr compactification $bG$ of $G$.
