Barlow surface

From Wikipedia, the free encyclopedia

In mathematics, a Barlow surface is one of the complex surfaces discovered by Rebecca Barlow (1984, 1985). They are simply connected surfaces of general type with p_g = 0. They are homeomorphic but not diffeomorphic to a projective plane blown up in 8 points. The Hodge diamond for the Barlow surfaces is:

		1
	0		0
0		9		0
	0		0
		1
