On the conformal‐biharmonic stability of the identity map of Einstein manifolds
Bulletin of the London Mathematical Society, Volume 58, Issue 11, November 2026.Abstract The identity map of an Einstein manifold is a critical point of both the classical energy functional and the conformal‐bienergy functional. In this paper, we investigate the conformal‐biharmonic stability of the identity map of compact Einstein manifolds of dimension at least four and with nonnegative scalar curvature, and we compare it with ...

Foliation of null cones by surfaces of constant spacetime mean curvature near MOTS
Journal of the London Mathematical Society, Volume 114, Issue 5, November 2026.Abstract Marginally outer trapped surfaces (MOTS) in spacetimes are well‐known to indicate the existence of black holes. Using flow techniques, we prove that a neighbourhood of a stable MOTS in a null cone may be foliated by hypersurfaces of constant spacetime mean curvature.

Topological and geometric rigidity of nonnegatively curved submanifolds
Bulletin of the London Mathematical Society, Volume 58, Issue 10, October 2026.Abstract We investigate the topology and geometry of compact submanifolds in space forms of nonnegative curvature satisfying a lower bound on the sectional curvature that depends only on the length of the mean curvature vector of the immersion. We show that this condition imposes strong constraints on either the topology or geometry of the submanifold.

GENERIC QR-SUBMANIFOLDS OF QUATERNION KAEHLER MANIFOLDS
, 2021 In this paper, generic QR-submanifolds of a quaternion Kaehler manifold are introduced as a generalization of QR-submanifolds and real hypersurfaces of a quaternion Kaehler manifold.

Complete $λ$-submanifolds in Gauss spaces [PDF]
, 2023 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.

Bordered Floer homology, handlebody detection, and compressing diffeomorphisms
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract We show that, up to connected sums with integer homology L$L$‐spaces, bordered Floer homology detects handlebodies, as well as whether a mapping class extends over a given handlebody or compression body. Using this, we combine ideas of Casson–Long with the theory of train tracks to give an algorithm using bordered Floer homology to detect ...

Reducibility of complex submanifolds of the complex euclidean spaces [PDF]
, 2000 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.
