[图书][B] Lattice theory: special topics and applications

GA Gratzer, F Wehrung - 2016 - Springer
George Grätzer started writing his General Lattice Theory in 1968. It was published in 1978.
It set out “to discuss in depth the basics of general lattice theory.” Almost 900 exercises, 193 …

G Czédli, G Grätzer - Lattice Theory: Special Topics and Applications …, 2014 - Springer
While the study of planar lattices goes back to the 1970s (KA Baker, PC Fishburn, and FS
Roberts [20] and D. Kelly and I. Rival [223]), a systematic study of planar semimodular …

Optimal implicational bases for finite modular lattices

M Wild - Quaestiones Mathematicae, 2000 - Taylor & Francis
Each finite closure system, whence each finite lattice, can be described in terms of"
implicational bases"(called" covers of functional dependencies" in relational database …

A cover-preserving embedding of semimodular lattices into geometric lattices

G Czédli, ET Schmidt - Advances in Mathematics, 2010 - Elsevier
Extending former results by G. Grätzer and EW Kiss (1986)[5] and M. Wild (1993)[9] on finite
(upper) semimodular lattices, we prove that each semimodular lattice L of finite length has a …

Revisiting Faigle geometries from a perspective of semimodular lattices

G Czédli - arXiv preprint arXiv:2107.10202, 2021 - arxiv.org
In 1980, U. Faigle introduced a sort of finite geometries on posets that are in bijective
correspondence with finite semimodular lattices. His result has almost been forgotten in …

Cover-preserving order embeddings into Boolean lattices

M Wild - Order, 1992 - Springer
It is not known which finite graphs occur as induced subgraphs of a hypercube. This is
relevant in the theory of parallel computing. The ordered version of the problem is: Which …

Generating subspace lattices, their direct products, and their direct powers

G Czédli - Acta Scientiarum Mathematicarum, 2024 - Springer
In 2008, László Zádori proved that the lattice S ub (V) of all subspaces of a vector space V of
finite dimension at least 3 over a finite field F has a 5-element generating set; in other words …

Isometrical embeddings of lattices into geometric lattices

B Skublics - Order, 2013 - Springer
A lattice is said to be finite height generated if it is complete and every element is the join of
some elements of finite height. Extending former results by Grätzer and Kiss (Order 2: 351 …

[图书][B] Some results on semimodular lattices

G Czédli, ET Schmidt - 2010 - researchgate.net
Some recent results on semimodular lattices are surveyed, and some related results are
given. The topics include a strong form of the Jordan-Hölder theorem, the semimodularity of …
