Topology Aware Stream Surfaces
Computer Graphics Forum, 2010AbstractWe present an algorithm that allows stream surfaces to recognize and adapt to vector field topology. Standard stream surface algorithms either refine the surface uncontrolled near critical points which slows down the computation considerably and may lead to a poor surface approximation.

Topological Approach to Quantum Surfaces
Communications in Mathematical Physics, 1999A topological approach to quantisation of closed surfaces is presented. This is done by imposing the following ``minimal'' requirements for a quantisation \(R\) of a closed Riemann surface \(\Sigma\) of genus \(g\geq 2\): \(R\) is a unital \(C^*\)-algebra, both \(R\) and \(C(\Sigma)\) are fibres in a continuous family of \(C^*\)-algebras over a path ...

Our aim in this section is to show that a compact orientable surface is homeomorphic to a sphere with handles, under the assumption that the surface can be triangulated. The idea is to “flatten” it out, to realize the surface as a polygon in the plane, with certain identifications on the boundary edges, and then, by cutting and pasting, to simplify ...

Corneal Surface Disease Topology
International Ophthalmology Clinics, 1998The specific morphology and distribution of corneal surface lesions may point toward a specific diagnosis and pathogenesis in individual cases (see Fig 1). Staining lesions may be fine (e.g., staphylococcal) or punctate (e.g., keratitis sicca). The size and appearance of staining and nonstaining lesions of the epithelium and subepithelial cornea may be

On Topological Classification of A-Diffeomorphisms of Surfaces
Journal of Dynamical and Control Systems, 2000This paper is a review of results obtained by the author and related to the topological classification of discrete dynamical systems (cascades) defined on an orientable smooth closed surface \({\mathcal A}_g\) of genus \(g\geq 0\). Topics are: 1) topological classification of one-dimensional basic sets via automorphisms of fundamental groups, 2 ...

The Topological Theory of Frechet Surfaces
The Annals of Mathematics, 1944The object of this paper is the study of surfaces. As the title indicates we do not propose to consider all the mathematical entities to which the term surface has been applied, and, in fact, our first obligation is to define precisely the objects of our attention.

Dynamics of rough surfaces with an arbitrary topology
Physical Review E, 1994A model for kinetic growth is presented that allows for overhangs and arbitrary topologies of the growing interface. Numerical studies of the model show that with a choice of the aggregation mechanism equivalent to the one leading to the Kardar-Parisi-Zhang (KPZ) equation [Phys. Rev. Lett. 56, 889 (1986)], we indeed obtain the KPZ results.
