On Goldie absolute direct summands in modular lattices [PDF]

open access: yesMathematica Bohemica, 2023
Absolute direct summand in lattices is defined and some of its properties in modular lattices are studied. It is shown that in a certain class of modular lattices, the direct sum of two elements has absolute direct summand if and only if the elements are

Pasting and modular lattices [PDF]

open access: yesProceedings of the American Mathematical Society, 1989
A classical lattice construction of R. P. Dilworth is the gluing of two lattices. A number of recent papers by A. Slavík, A. Day, and J. Ježek investigated a generalization: pasting. In this note we prove that by pasting two finite modular lattices, one obtains a modular lattice.

Generalizations of supplemented lattices

open access: yesAKCE International Journal of Graphs and Combinatorics, 2019
Some generalizations of the concept of a supplemented lattice, namely a soc-supplemented-lattice, soc-amply-supplemented-lattice, soc-weak-supplemented-lattice, soc-⊕-supplemented-lattice and completely soc-⊕-supplemented-lattice are introduced.

Cofinitely Supplemented Modular Lattices [PDF]

open access: yesArabian Journal for Science and Engineering, 2011
In this paper it is shown that a lattice L is a cofinitely supplemented lattice if and only if every maximal element of L has a supplement in L. If a/0 is a cofinitely supplemented sublattice and 1/a has no maximal element, then L is cofinitely supplemented.

Self-Reconfiguration Sequence of Lattice Modular Soft Robots

open access: yesShanghai Jiaotong Daxue xuebao, 2021
A lattice self-reconfigurable modular soft robot based on the expansion-contraction motion rule is designed, which is composed of several soft modules, each of which is composed of a silica gel main body with positive hexahedron configuration and a ...

Orthogonality and complementation in the lattice of subspaces of a finite vector space [PDF]

open access: yesMathematica Bohemica, 2022
We investigate the lattice $ L( V)$ of subspaces of an $m$-dimensional vector space $ V$ over a finite field ${\rm GF}(q)$ with a prime power $q=p^n$ together with the unary operation of orthogonality.

Modularity in topological lattices [PDF]

open access: yesProceedings of the American Mathematical Society, 1969
The purpose of this note is to establish that for topological lattices of suitably small breadth, connectedness implies modularity without an exploitation of compactness. L will denote a topological lattice, that is a Hausdorff topological space with continuous binary operations V and A for which (L, V, A) is a lattice. For a more explicit presentation

Duality web on a 3D Euclidean lattice and manifestation of hidden symmetries

open access: yesJournal of High Energy Physics, 2019
We generalize our previous lattice construction of the abelian bosonization duality in 2 + 1 dimensions to the entire web of dualities as well as the N f = 2 self-duality, via the lattice implementation of a set of modular transformations in the theory ...

Goldie extending elements in modular lattices [PDF]

open access: yesMathematica Bohemica, 2017
The concept of a Goldie extending module is generalized to a Goldie extending element in a lattice. An element $a$ of a lattice $L$ with $0$ is said to be a Goldie extending element if and only if for every $b \leq a$ there exists a direct summand $c$ of

On some classes of sublattices of the subgroup lattice

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
In this paper G always denotes a group. If K and H are subgroups of G, where K is a normal subgroup of H, then the factor group of H by K is called a section of G.
