Groupoid

Category where every morphism is invertible; generalization of a group

homotopy theory, a groupoid (less often Brandt groupoid or virtual group) generalises the notion of group in several equivalent ways. A groupoid can be seen

Mather

English : occupational name for a mower or reaper of grass or hay, Old English mÇ£Ã°ere. Compare Mead, Mower. Hay was formerly of great importance, not only as feed for animals in winter but also for bedding.English : in southern Lancashire, where it has long been a common surname, it is probably a relatively late development of Madder (see Mader).English : The prominent Mather family of New England were established in America by Richard Mather (1596â€“1669) in 1635. He was a Puritan clergyman from a well-established family of Lowton, Lancashire, England. After he emigrated, he was in great demand as a preacher, finally settling in Dorchester, MA. His son Increase Mather (1639â€“1723) was a diplomat and president of Harvard. He married his step-sister Maria Cotton, herself the daughter of an eminent Puritan divine, John Cotton. Their son Cotton Mather (1663â€“1728) bore both family names. The latter was a minister who is remembered for his part in witchcraft trials, but he was also a man of science and a fellow of the Royal Society in London.
