The theory of finite type submanifolds was introduced by the first author in late 1970s and it
has become a useful tool for investigation of submanifolds. Later, the first author and P …

We set up the new models of product manifolds, namely a generalized circular cylinder and
a generalized hyperbolic cylinder as cylindrical types of ruled submanifold in Minkowski …

In this paper, we study biconservative immersions into the semi-Riemannian space form R^
4_2 (c) R 2 4 (c) of dimension 4, index 2 and constant curvature c ∈ {0,-1, 1\} c∈ 0,-1, 1 …

Bu makalede, genelleştirilmiş 1-tipinden Gauss tasvirine sahip Minkowski uzayındaki dönel
yüzeyler ve regle alt manifoldları üzerine çalışılmıştır. İlk olarak, ikinci çeşit noktasal 1 …

Основной задачей классической многомерной дифференциальной геометрии является
исследование свойств различных n-поверхностей. Часто в этих исследованиях …

In this talk, we present a survey of some new classes of submanifolds in the pseudo-
Euclidean spaces that we obtained after our recent studies. Firstly, we study a class of quasi …

A Lorentz surface in the pseudo-Euclidean 4-space with neutral metric is called quasi-
minimal if its mean curvature vector is lightlike at each point. We prove that any quasi …

Строение замкнутых и незамкнутых регулярных гиперповерхностей с инъективным
гауссовым отображением достаточно хорошо изучено. При решении ряда задач …

In this paper we study biconservative immersions into the semi-Riemannian space form $ R^
4_2 (c) $ of dimension 4, index 2 and constant curvature, where $ c\in\{0,-1, 1\} $. First, we …

A mapping φ: M→ EN S is said to be finite type if it can be expressed as φ= φ0+ φ1+·+ φk for
a constant vector φ0 and some eigenvectors φ1,..., φk of the Laplace operator∆ of M, where …
