Fundamental groups, geometry, and some papers of Scott

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract Throughout the history of 3‐manifolds, the fundamental group has played a central role. There is a list of reasons for that, and exactly what that role is has evolved over time, but it has always been a player. The papers under consideration here all written by G.

C.T.C. Wall's 1964 articles on 4‐manifolds

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract I survey C. T. C. Wall's influential papers, ‘Diffeomorphisms of 4‐manifolds’ and ‘On simply‐connected 4‐manifolds’, published in 1964 on pp. 131–149 of volume 39 of the Journal of the London Mathematical Society.

Theta divisors and permutohedra

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We establish an intriguing relation of the smooth theta divisor Θn$\Theta ^n$ with permutohedron Πn$\Pi ^n$ and the corresponding toric variety XΠn$X_\Pi ^n$. In particular, we show that the generalised Todd genus of the theta divisor Θn$\Theta ^n$ coincides with h$h$‐polynomial of permutohedron Πn$\Pi ^n$ and thus is different from the same ...

Role of shape operator in warped product submanifolds of nearly cosymplectic manifolds

AIMS Mathematics, 2020
In this paper, first, we find the integrability theorems for the invariant and slant distributions which appeared in the concept of semi-slant submanifolds.

A Kernel Based Neighborhood Discriminant Submanifold Learning for Pattern Classification

Journal of Applied Mathematics, 2014
We propose a novel method, called Kernel Neighborhood Discriminant Analysis (KNDA), which can be regarded as a supervised kernel extension of Locality Preserving Projection (LPP).

Positively curved Kaehler submanifolds [PDF]

Proceedings of the American Mathematical Society, 1985
In this note we prove that if the holomorphic curvature of a compact Kaehler submanifold in the complex projective space is bigger than 1 2 \tfrac {1}{2} , then it is totally geodesic.

Distributions in spaces with thick submanifolds

Electronic Research Archive
We have presented the construction of a theory of distributions (generalized functions) with a 'thick submanifold', that is, a new theory of thick distributions on $ \mathbb{R}^n $ whose domain contains a smooth submanifold on which the test functions ...
