Mission‐Aligned Learning‐Informed Control of Autonomous Systems: Formulation and Foundations

open access: yesExpert Systems, Volume 43, Issue 11, November 2026.
ABSTRACT Research, innovation and practical capital investment have been increasing rapidly toward the realization of autonomous physical agents. This includes industrial and service robots, unmanned aerial vehicles, embedded control devices, and a number of other realizations of cybernetic/mechatronic implementations of intelligent autonomous devices.

An Optimal Control Framework for Multi‐Species Harvesting in the Southern Black Sea

open access: yesNatural Resource Modeling, Volume 39, Issue 4, November 2026.
ABSTRACT The management of marine fisheries requires balancing ecological sustainability with economic profitability, particularly in ecosystems vulnerable to overexploitation. This study develops a multi‐species optimal control modeling framework for the southern Black Sea, focusing on three key species: horse mackerel (Trachurus mediterraneus) as ...

On the conformal‐biharmonic stability of the identity map of Einstein manifolds

open access: yesBulletin 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

open access: yesJournal 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.

Johnson–Schwartzman gap labeling for metric and discrete decorated graphs

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 5, November 2026.
Abstract We study Schrödinger operators on metric and discrete decorated graphs. The values taken by the integrated density of states (IDS) on spectral gaps are called gap labels. A natural question is which gap labels can occur. We answer this for graphs arising from uniquely ergodic one‐dimensional dynamical systems by proving Johnson–Schwartzman gap‐

Seifert cobordisms and the Chen–Yang volume conjecture

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 5, November 2026.
Abstract We study the large‐r$r$ asymptotic behavior of the Turaev–Viro invariants TVr(M;e2πir)$TV_r(M; e^{\frac{2\pi i}{r}})$ of 3‐manifolds with toroidal boundary, under the operation of gluing a Seifert‐fibered 3‐manifold along a component of ∂M$\partial M$. We show that the Turaev–Viro invariants volume conjecture is closed under this operation. As
