Ernst Leonard Lindelöf ( Swedish pronunciation: [ˈlɪ̂nːdɛˌløːv] ; 7 March 1870 – 4 June 1946) was a Finnish mathematician, who made contributions in real analysis , complex analysis and topology . Lindelöf spaces are named after him. He was the son of mathematician Lorenz Leonard Lindelöf and brother of the philologist Uno Lorenz Lindelöf [ fi ] .
