Explicit equations for new fake projective planes in smooth surfaces, indicating potential for computational methods.
We discover a simple construction of a four-dimensional family of smooth surfaces of general type with p g ( S ) = q ( S ) = 0 p_g(S)=q(S)=0 , K S 2 = 3 K^2_S=3 with cyclic fundamental group C 14 C₁₄ . We use a degeneration of the surfaces in this family to find (complicated) explicit equations of six new pairs of fake projective planes. Our methods for finding new fake projective planes involve nontrivial computer calculations which we hope will be applicable in other settings.
