Complete $\lambda$-submanifolds in Gauss spaces [PDF]
In this paper, we study $\lambda$-submanifolds of arbitrary codimensions in Gauss spaces. These submanifolds can be seen as natural generalizations of self-shrinker and $\lambda$-hypersurfaces.

New results toward the classification of biharmonic submanifolds in 𝕊n
We prove some new rigidity results for proper biharmonic immer- sions in Sn of the following types: Dupin hypersurfaces; hypersurfaces, both compact and non-compact, with bounded norm of the second fun- damental form; hypersurfaces satisfying intrinsic ...

ON THE GEOMETRY OF PARACOMPLEX SUBMANIFOLDS
The paracomplex submanifolds \(M\) in an almost parahermitian manifold (\(\overline M,\overline J,\overline g)\) with \(\overline J^2=I\), \(\overline g(X,\overline JY)+\overline g(\overline JX,Y)=0\) are characterized by \(\overline J(T_xM)=T_xM\) [see \textit{V. Cruceanu}, \textit{P. Fortuny} and \textit{P. M. Gradea} in Rocky Mt. J. Math. 26, 83-115

On normal CR-submanifolds of S-manifolds [PDF]
Many authors have studied the geometry of submanifolds of Kaehlerian and Sasakian manifolds. On the other hand, David E. Blair has initiated the study of S-manifolds, which reduce, in particular cases, to Sasakian manifolds ([1, 2]). I. Mihai ([8]) and L.

Certain Submanifolds of Hsu-structure Manifolds [PDF]
In this paper, authors have studied Hsu-structure manifolds and submanifolds. Submanifolds immersed in Hsu-structure manifold and (f, g, A1, A2, T1, T2) -Hsu metric structure manifolds have been studied.

Reducibility of complex submanifolds of the complex euclidean spaces [PDF]
Let M be a simply connected complex submanifold of CN. We prove that M is irreducible, up a totally geodesic factor,if and only if the normal holonomy group acts irreducibly.

Screen Cauchy–Riemann (SCR)-lightlike submanifolds of metallic semi-Riemannian manifolds [PDF]
PurposeThe screen Cauchy–Riemann (SCR)-lightlike submanifold is an important class of submanifolds of semi-Riemannian manifolds. It contains various other classes of submanifolds as its sub-cases. It has been studied under various ambient space.

Brownian Motion on a Submanifold [PDF]
Consider an \(n\)-dimensional complete Riemannian manifold \(N\), and a closed \(m\)-dimensional submanifold \(M\). Using that the Laplacian on \(N\) is got by projection of the horizontal Laplacian on \(O(N): (\Delta^N\varphi)\circ\pi= \sum^n_{i=1} (H^N_i)^2(\varphi\circ\pi)\), one obtains classically the Brownian motion on \(N\) as \(\pi(p^N_t ...
