String topology via the coHochschild complex and local intersections

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract We construct an algebraic model for the Chas–Sullivan product and the Goresky–Hingston coproduct in string topology. The construction takes as its initial input a simplicial complex equipped with a local pairing on its simplicial chains, for instance, a homology manifold with its local intersection pairing.

An elementary approach to Wehrl‐type entropy bounds in quantitative form

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 1, July 2026.
Abstract We consider the problem of the stability (with sharp exponent) of the Lieb–Solovej inequality for symmetric SU(N)$SU(N)$ coherent states, which was obtained only recently by the authors. Here, we propose an elementary proof of this result, based on reformulating the Wehrl‐type entropy as a function defined on the unit sphere in Cd$\mathbb {C ...

A Note on Triple Systems and Totally Geodesic Submanifolds in a Homogeneous Space [PDF]

open access: yesNagoya Mathematical Journal, 1968
In the study of nonassociative algebras various “triple systems” frequently arise from the associator function and other multilinear objects. In particular Lie triple systems arise in the study of Jordan algebras and a generalization of a Lie triple system arises in Malcev algebras.

On the tightness of left‐invariant contact structures

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract We prove that all left‐invariant contact structures on three‐dimensional Lie groups are tight. The argument is based on Riemannian methods and establishes a unique factorization property for any Lie group admitting a left‐invariant contact structure, other than SU(2)$\mathrm{SU}(2)$. We then make use of such factorization property to construct

Totally geodesic submanifolds of Teichmuller space [PDF]

open access: yes
We show that any totally geodesic submanifold of Teichmuller space of dimension greater than one covers a totally geodesic subvariety, and only finitely many totally geodesic subvarieties of dimension greater than one exist in each moduli space.This is a

Study of bi-f-harmonic curve along immersions

open access: yesMiskolc Mathematical Notes
In this paper, we characterize the bi-f-harmonic curve on surfaces and then we study the submanifold of a Riemannian manifold using the bi-f-harmonic curve.

Exponentially Harmonic Maps into Spheres

open access: yesAxioms, 2018
We study smooth exponentially harmonic maps from a compact, connected, orientable Riemannian manifold M into a sphere S m ⊂ R m + 1 .

Transverse totally geodesic submanifolds of the tangent bundle

open access: yesPublicationes Mathematicae Debrecen, 2004
It is well-known that if $ξ$ is a smooth vector field on a given Riemannian manifold $M^n$ then $ξ$ naturally defines a submanifold $ξ(M^n)$ transverse to the fibers of the tangent bundle $TM^n$ with Sasaki metric. In this paper, we are interested in transverse totally geodesic submanifolds of the tangent bundle.

Cohomogeneity‐one solitons in Laplacian flow: Local, smoothly‐closing and steady solitons

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We initiate a systematic study of cohomogeneity‐one solitons in Bryant's Laplacian flow of closed G2$\text{G}_2$‐structures on a 7‐manifold, motivated by the problem of understanding finite‐time singularities of that flow. Here, we focus on solitons with symmetry groups Sp(2)${\rm Sp}(2)$ and SU(3)${\rm SU}(3)$; in both cases, we prove the ...

Pseudo-Riemannian manifolds with totally geodesic bisectors

open access: yes, 1975
Let M M be a pseudo-Riemannian manifold. Locally a distance function may be defined. The bisector of two points is the set of points equidistant from these two points.
