On Fico's Lemmata and the homotopy type of certain gyrations
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract We undertake to determine the homotopy type of gyrations of sphere products and of connected sums, thereby generalising results known in earlier literature as ‘Fico's Lemmata’ which underpin gyrations in their original formulation from geometric topology.

Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract We classify fibered ribbon pretzel knots up to mutation. The classification is complete, except perhaps for members of Lecuona's “exceptional” family of Lecuona [Algebr. Geom. Topol. 15 (2015), no. 4, 2133–2173]. The result is obtained by combining lattice embedding techniques with Gabai's classification of fibered pretzel knots, and ...

Contact exponent and the Milnor number of plane curve singularities [PDF]
, 2019 We investigate properties of the contact exponent (in the sense of Hironaka [Hi]) of plane algebroid curve singularities over algebraically closed fields of arbitrary characteristic.

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 ...

Beyond the Hodge theorem: Curl and asymmetric pseudodifferential projections
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract We develop a new approach to the study of spectral asymmetry. Working with the operator curl:=∗d$\operatorname{curl}:={*}\mathrm{d}$ on a connected oriented closed Riemannian 3‐manifold, we construct, by means of microlocal analysis, the asymmetry operator — a scalar pseudodifferential operator of order −3$-3$.

The jump of the Milnor number of quasihomogeneous singularities for linear deformations
, 2023 The jump of the Milnor number of an isolated singularity $f_0$ is the minimal non-zero difference between the Milnor numbers of $f_0$ and one of its deformations $f_s$.

Designing Statewide Drone Delivery Networks in Rural Contexts: A Multiobjective Approach
Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.Last‐mile parcel delivery remains a major challenge in rural areas where unpaved roads, long travel distances, and sparse demand limit the efficiency of truck‐based logistics. This study evaluates the use of cargo drones as a replacement for trucks, focusing on the design of a statewide delivery network supported by multimodal hubs.

Milnor numbers, spanning trees, and the Alexander–Conway polynomial
Advances in Mathematics, 2003 We study relations between the Alexander-Conway polynomial $\nabla_L$ and Milnor higher linking numbers of links from the point of view of finite-type (Vassiliev) invariants. We give a formula for the first non-vanishing coefficient of $\nabla_L$ of an m-component link L all of whose Milnor numbers $μ_{i_1... i_p}$ vanish for $p\le n$.

An application of bivariant theory to Milnor classes
, 2001 The notion of the Milnor number of an isolated singularity of a hypersurface has been generalized to the so-called “Milnor class” in such a way that the degree of the zero-dimensional component of the Milnor class is nothing but the Parusiński ...
