Lattices with lots of congruence energy 有很多同余能量的晶格

{"title":"Lattices with lots of congruence energy","authors":"Gábor Czédli","doi":"10.30755/nsjom.15406","DOIUrl":"https://doi.org/10.30755/nsjom.15406","url":null,"abstract":"In 1978, motivated by E. H\"uckel's work in quantum chemistry, I. Gutman introduced the concept of the energy of a finite simple graph $G$ as the sum of the absolute values of the eigenvalues of the adjacency matrix of $G$. At the time of writing, the MathSciNet search for\"Title=(graph energy) AND Review Text=(eigenvalue)\"returns 351 publications, most of which going after Gutman's definition. A congruence $alpha$ of a finite algebra $A$ turns $A$ into a simple graph: we connect $xneq yin A$ by an edge iff $(x,y)inalpha$; we let En$(alpha)$ be the energy of this graph. We introduce the congruence energy CE$(A)$ of $A$ by CE$(A):=sum{$En$(alpha): alphain$ Con$(A)}$. Let LAT$(n)$ and CDA$(n)$ stand for the class of $n$-element lattices and that of $n$-element congruence distributive algebras of any type. For a class $mathcal X$, let CE$(mathcal X):= {$CE$(A): Ain mathcal X}$. We prove the following. (1) For $alphain A$, En$(alpha)/2$ is the height of $alpha$ in the equivalence lattice of $A$. (2) The largest number and the second largest number in CE(LAT($n$)) are $(n-1)cdot 2^{n-1}$ and, for $ngeq 4$, $(n-1)cdot 2^{n-2}+2^{n-3}$; these numbers are only witnessed by chains and lattices with exactly one two-element antichain, respectively. (3) The largest number in CE(CDA($n$)) is also $(n-1)cdot 2^{n-1}$, and if CE$(A)=(n-1)cdot 2^{n-1}$ for an $Ain$ CDA$(n)$, then Con$(A)$ is a boolean lattice with size $|$Con$(A)|=2^{n-1}$.","PeriodicalId":38723,"journal":{"name":"Novi Sad Journal of Mathematics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135765943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
