Primer of Subquasivariety Lattices

“This is a research monograph that reports on investigations, both classical and new, into the structure of subquasivariety lattices. ... This monograph is a study of the structure of lattices of the form Lq(K). In this monograph, relation symbols are permitted. ... The monograph spans 290 pages and has 10 chapters and three appendices.” (Keith A. Kearnes, Mathematical Reviews, April, 2024)
