Surfaces in Sol space foliated by circles
Rafael López, Ana Nistor
In this paper we study surfaces foliated by a uniparametric family of circles in the homogeneous space Sol. We prove that there do not exist such surfaces with zero mean curvat…
Surfaces in $\E^3$ making constant angle with Killing vector fields
Marian Ioan Munteanu, Ana Irina Nistor
In the present paper we classify curves and surfaces in Euclidean space which make constant angle with a certain Killing vector field. Moreover, we characterize the catenoid an…
On certain surfaces in the Euclidean space
Marian Ioan Munteanu, Ana Irina Nistor
In the present paper we classify all surfaces in $\E^3$ with a canonical principal direction. Examples of these type of surfaces are constructed. We prove that the only minimal sur…
Canonical Coordinates and Principal Directions for Surfaces in $\H^2\times\R$
Franki Dillen, Marian Ioan Munteanu, Ana Irina Nistor
In this paper we characterize and classify surfaces in which have a canonical principal direction. Here denotes the hyperbolic p…
Certain Constant Angle Surfaces Constructed on Curves
Ana-Irina Nistor
In this paper we classify certain special ruled surfaces in under the general theorem of characterization of constant angle surfaces. We study the tangent developable and co…
On the Geometry of the Second Fundamental Form of Translation Surfaces in E3
Marian Ioan Munteanu, Ana Irina Nistor
In this paper we study the second fundamental form of translation surfaces in E3. We give a non-existence result for polynomial translation surfaces in E3 with vanishing second Gau…
