Homeomorphisms of twodimensional manifolds
 Houston J. Math
, 1985
"... homeomorphisms of 2manifolds apparently has been hampered by the existence of homeomorphisms with widely erratic behavior (see, for example [2], [3], [9]). While even diffeomorphisms are frequently nonflowable, the behavior of homeomorphisms (for example, in the neighborhood of fixed points) can b ..."

TRANSITIVE FLOWS ON TWODIMENSIONAL MANIFOLDS
"... A flow O = {<frt\teU} on a space M is strongly transitive provided that there is a dense Gs set G in M such that for each p in G the trajectory of p, T(p) = {0,(/>)f e R} is dense in both time directions in M. In this case, we shall say that the space M is admissible. Thus, for example, the ..."

The Calderon problem for twodimensional manifolds by the BCmethod
, 2002
"... This paper is a corrected and extended version of the preprint [3]. Our results are the following: ffl we show a relationship between the Calderon problem and Function Algebras and give a new proof of Theorem 1 exploiting this relationship; ffl a simple formula (see (1.6)) linking the DNmap to the ..."

Invertible Linear Differential Operators on TwoDimensional Manifolds
"... . In case of two independent variables invertible linear differential operators structure is described. It is proved that a twosided invertible operator can be written as a composition of triangular invertible operators in the stable sense. The form to which a leftinvertible operator can be reduce ..."

Some twodimensional manifolds with affine connections
"... Here we present some simple manifolds with affine connections to get some feeling for how things like curvature manifest themselves. All the affine connections we consider will be LeviCivita connections and so are torsion free. Recall that the LeviCivita connection ..."

Linearizability of dwebs, d ≥ 4, on twodimensional manifolds
, 2008
"... We find d − 2 relative differential invariants for a dweb, d ≥ 4, on a twodimensional manifold and prove that their vanishing is necessary and sufficient for a dweb to be linearizable. If one writes the above invariants in terms of web functions f(x, y) and g4(x, y),..., gd(x, y), then necessary ..."

Radial Control Algorithm for Two Dimensional Manifold Computation
, 2013
"... Abstract: The Algorithms of manifold computation are still remained to be optimized. The low computing errors and high computing speed are always two incompatible factors. This paper takes the discrete system as study object and combines the manifold extending methods with radial control algorithm. ..."

EXPLICIT INTEGRABLE SYSTEMS ON TWO DIMENSIONAL MANIFOLDS WITH A CUBIC FIRST INTEGRAL
, 2010
"... A few years ago Selivanova gave an existence proof for some integrable models, in fact geodesic flows on two dimensional manifolds, with a cubic first integral. However the explicit form of these models hinged on the solution of a nonlinear third order ordinary differential equation which could not ..."
