List of things named after James Joseph Sylvester

Template:Short description The mathematician J. J. Sylvester was known for his ability to coin new names and new notation for mathematical objects,<ref>Template:Citation.</ref> not based on his own name. Nevertheless, many objects and results in mathematics have come to be named after him:<ref>MathSciNet lists over 500 mathematics articles with "Sylvester" in their titles, most of which concern mathematical subjects named after Sylvester.</ref> Template:Div col
