Linear difference equations, frieze patterns, and the combinatorial Gale transform
Forum of Mathematics, Sigma, 2014 We study the space of linear difference equations with periodic coefficients and (anti)periodic solutions. We show that this space is isomorphic to the space of tame frieze patterns and closely related to the moduli space of configurations of points in ...

Conformal deformations preserving the Gauss map [PDF]
Pacific Journal of Mathematics, 1992 We establish conditions on a conformal immersion of a Riemannian manifold in the Euclidean space for the existence of another conformal immersion with the same Gauss map. For surfaces in \(\mathbb{R}^ 3\) these conditions are expressed by a partial differential equation envolving the principal curvatures.

A special case of rational θs for terminating θ-expansions [PDF]
Surveys in Mathematics and its Applications, 2013 There have been quite a few generalizations of the usual continued fraction expansions over the last few years. One very special generalization deals with θ-continued fraction expansions or simply θ-expansions introduced by Bhattacharya and Goswami [A ...

On the Gauss Map of Surfaces of Revolution with Lightlike Axis in Minkowski 3-Space
Journal of Function Spaces and Applications, 2013 By studying the Gauss map G and Laplace operator Δh of the second fundamental form h, we will classify surfaces of revolution with a lightlike axis in 3-dimensional Minkowski space and also obtain the surface of Enneper of the 2nd kind, the surface of ...

Hypersurfaces with planar lines of curvature in Euclidean Space
Selecciones Matemáticas, 2017 In this work, we present explicit parameterizations of hypersurfaces parameterized by lines of curvature with prescribed Gauss map and we characterize the hypersurfaces with planar curvature lines.

On the Gauss maps of singular projective varieties [PDF]
Journal of the Australian Mathematical Society, 2002 AbstractHere we study the dimension δ(m, X) of the general fibers of the m-Gaussian map of a singular n-dimensional variety X ⊂ Pn. We show that for all integers a, b, c, d with n ≦ a < b ≦ c < d ≦ N − 1 and a + d = b + c we have δ (a, X) + δ(d, X) > δ(b, X) + δ(c, X).
