Some generalizations of torsion-free Crawley groups
No full textsummary:In this paper we investigate two new classes of torsion-free Abelian groups which arise in a natural way from the notion of a torsion-free Crawley group. A group is said to be an Erdős group if for any pair of isomorphic pure subgroups with , there is an automorphism of mapping onto ; it is said to be a weak Crawley group if for any pair of isomorphic dense maximal pure subgroups, there is an automorphism mapping onto . We show that these classes are extensive and pay attention to the relationship of the Baer-Specker group to these classes. In particular, we show that the class of Crawley groups is strictly contained in the class of weak Crawley groups and that the class of Erdős groups is strictly contained in the class of weak Crawley groups

Waverly B. Crawley interview (2000-04-27)
No full textPart of a series of interviews conducted as part of a Carver-VCU Partnership project documenting the history of the Carver neighborhood in Richmond, Virginia. Waverly Robert Crawley, Jr., who was raised in the Carver neighborhood of Richmond, Va., recounts his memories of growing up there in the 1930s. Mr. Crawley describes the origins of his name; places he remembers from the neighborhood; individuals he admired and Carver\u27s early origins as Sheep Hill. He also reminisces about Carver social life and conditions; effects of desegregation; and his thoughts on the future of the Carver neighborhood.https://scholarscompass.vcu.edu/car/1002/thumbnail.jp

Wheeler, 1924), by monotypy.</p> <p> <b>Diagnosis.</b> This genus can be recognized by a combination of the following characteristics of the worker caste: i) prominent costate sculpture on most of body surface, ii) large eyes, iii) exposed antennal sockets, iv) two spurs on mid and hind tibiae, and v) pretarsal claws with a tooth (BOROWIEC 2016).</p> <p> <b> Key to <i>Chrysapace</i> species based onthe worker caste.</b> The key to valid species is provided below.

Maxine Crawley and Linda Patton
No full textThis 1963 photograph shows Maxine Crawley and Linda Patton winning the Delta Airlines Award trophy at the Mountain Youth Jamboree. Founder and director of the Mountain Youth Jamboree, Hubert H. Hayes (1901-1964) auditioned and directed youth to perform in folk dance, music, and folk and ballad singing. The jamboree was held in the Asheville City Auditorium (now known as Thomas Wolfe Auditorium) from 1948 to 1973, and Hayes’ wife, Leona Trantham Hayes (1913-1989) continued to direct the program after his death in 1964. Hubert Hayes was an author, playwright, and alumni of Duke University

Semilinear clannish algebras
No full textBennett-Tennenhaus R, Crawley-Boevey WW. Semilinear clannish algebras. Proceedings of the London Mathematical Society . 2024;129(4): e12637.We define a class of associative algebras generalizing 'clannish algebras', as introduced by the second author, but also incorporating semilinear structure, like a skew polynomial ring. Clannish algebras generalize the well-known 'string algebras' introduced by Butler and Ringel. Our main result is the classification of finite-dimensional indecomposable modules for these new algebras
