    Holland's Black Swamp book

    • When European settlers reached the upper Midwest in the early 19th century, they encountered a vast swamp, roughly 25 x 100 miles in extent, abutting the southern edge of Lake Erie. The Black Swamp was impenetrable during most of the year; horses sank up to their bellies, and malaria was endemic to the area. Wildlife was abundant; flocks of game birds used to darken the sun. The backbreaking labor of several generations was required to drain the swamp, and the resulting farm land became some of the richest in the Midwest. However, the ecological consequences of development have been dire, with frequent toxic algae blooms in Lake Erie due to fertilizer runoff.
      In 1972 Charles Holland joined the faculty of Bowling Green State University, located in Toledo, Ohio, site of the former Black Swamp. Charles was a leading light in research on lattice ordered groups and related topics, and it was his habit to carry a book to conferences and to ask colleagues to record questions, conjectures, and comments. The Black Swamp book is a record of the development of the theory of l-groups and related subjects over several decades, handwritten by numerous mathematicians on numerous occasions in numerous contexts and locations.
      Many of these problems appear in the article "Unsolved Problems in Ordered and Orderable Groups," by Bludov, Glass, Kopytov, and Medvedev, https://arxiv.org/pdf/0906.2621.pdf. As the title suggests, this list is heavily oriented towards group theory.
