Intrinsic and extrinsic geometry of random surfaces
We prove that the extrinsic Hausdorff dimension is always greater than or equal to the intrinsic Hausdorff dimension in models of triangulated random surfaces with action which is quadratic in the separation of vertices. We furthermore derive a few naive scaling relations which relate the intrinsic Hausdorff dimension to other critical exponents. These relations suggest that the intrinsic Hausd...
متن کاملA Study of Intrinsic and Extrinsic Motivation Iranian mysticism gravamen
Gravamen is a kind of lyrical literature in which human tries own suffering and distress to reveal the audience. There are several types of gravamen. One of them is the mystical breakthrough that comes from the intrinsic and extrinsic motivation. Including Intrinsic motivations can be mentioned the sadness of separation from partner, the sadness of separation from partner, sensual temptations, ...
متن کاملStructure of Rational Open Surfaces with Non{positive Euler Characteristic
We study mainly connected conngurations of irreducible curves r i=1 C i on a nonsingular rational projective complex surface X such that the Euler characteristic (X n r i=1 C i) 0, hereby continuing a former conjecture of the author and work of Gurjar and Parameswaran. Roughly we show that any such connguration can be extended to another connguration s i=1 C i (r s) with still (X n s i=1 C i) 0...
متن کاملComplete surfaces with negative extrinsic curvature
N. V. Efimov [Efi64] proved that there is no complete, smooth surface in R with uniformly negative curvature. We extend this to isometric immersions in a 3-manifold with pinched curvature: if M has sectional curvature between two constants K2 and K3, then there exists K1 < min(K2, 0) such that M contains no smooth, complete immersed surface with curvature below K1. Optimal values of K1 are dete...
متن کاملHypercubic Random Surfaces with Extrinsic Curvature
We analyze a model of hypercubic random surfaces with an extrinsic curvature term in the action. We find a first order phase transition at finite coupling separating a branched polymer from a stable flat phase.
