Overduin and Wesson successfully eliminated the cylindrical assumption from this theory, while Coquereaux and Jadczyk were the first to consider this theory's G-invariant scheme.  Containing an extra scalar field known as the "dilation," this theory involves the "rolling up" of proposed higher dimensions in a process called spontaneous compactification.  First postulated by its namesakes to unify classical gravity and electromagnetism, FTP, identify this unified-field theory that proposes at least five space-time dimensions, named after its two German creators.
