Aspects of Data Modeling of Fused Surfaces with Planimetric Data in a Topographic Geodatabase
Raster TIN Accuracy
2015/7/6
As a result of building a topological surfaced geodatabase for the test area, the paper discuses the investigation of modeling 3D
surface data, and its fusion with other planinmetric modeled data, an...
Representations of the Kauffman skein algebra II: punctured surfaces
Representations of the Kauffman skein algebra II punctured surfaces Geometric Topology
2012/6/29
In earlier work, we constructed invariants of irreducible representations of the Kauffman skein algebra of a surface. We introduce here an inverse construction, which to a set of possible invariants a...
The minimal genus problem for elliptic surfaces
4-manifold elliptic surface diffeomorphism group minimal genus
2012/6/25
We partly solve the minimal genus problem for embedded surfaces in the case of elliptic 4-manifolds. This involves a certain restricted transitivity property of the action of the orientation preservin...
Skein algebras and cluster algebras of marked surfaces
Skein algebras cluster algebras marked surfaces Quantum Algebra Geometric Topology
2012/4/17
This paper defines several algebras associated to an oriented surface S with a finite set of marked points on the boundary. The first is the skein algebra Sk_q(S), which is spanned by links in the sur...
On visualization of the linearity problem for mapping class groups of surfaces
visualization linearity problem mapping class groups surfaces
2012/3/1
We derive two types of linearity conditions for mapping class groups of orientable surfaces; one for once-punctured surface, and the other for closed surface, respectively. For the once-punctured case...
Dynamics of random selfmaps of surfaces with boundary

2011/9/16
Abstract: We use Wagner's algorithm to estimate the number of periodic points of certain selfmaps on compact surfaces with boundary. When counting according to homotopy classes, we can use the asympto...
Computing the crosscap number of a knot using integer programming and normal surfaces
integer programming normal surfaces crosscap number of a knot Geometric Topology
2011/9/5
Abstract: The crosscap number of a knot is an invariant describing the non-orientable surface of smallest genus that the knot bounds. Unlike knot genus (its orientable counterpart), crosscap numbers a...
Degree three cohomology of function fields of surfaces
Degree three cohomology function fields of surfaces
2011/2/25
Let k be a global field or a local field. Class field theory says that every central division algebra over k is cyclic. If k contains lth roots of unity, for a prime l not equal to the characteristic ...
Upper bounds for the bondage number of graphs on topological surfaces
Bondage number Domination number Topological surface
2011/2/22
The bondage number b(G) of a graph G is the smallest number of edges of G whose removal from G results in a graph having the domination number larger than that of G. We show that, for a graph G having...
Complex Conjugation Equivariant Topology of Complex Surfaces
Equivariant Topology Complex Surfaces
2010/3/5
Suppose X is a non-singular complex surface defined over \R, which is a complete intersection constructed by the method of a small perturbation, and Y=X/\conj is its quotient by the complex conjugatio...
Determining the Topology of Real Algebraic Surfaces
Determining Topology Real Algebraic Surfaces
2013/9/9
An algorithm is proposed to determine the topology of an implicit real algebraic surface inR3. The algorithm consists of three steps:surface projection,projection curve topology determination and surf...
Topology Change and Vector Modules on Noncommutative Surfaces of Rotation
Topology Vector Modules Noncommutative Surfaces of Rotation
2010/10/29
A non associative, noncommutative algebra is defined that may be interpreted as a set of vector modules over a noncommutative surface of rotation. Two of these vector modules are identified with the ...
