Hochschild Cohomology of the Algebra of Conformal Endomorphisms
Известия Иркутского государственного университета: Серия "Математика"It was proved by I. Dolguntseva (St. Peterburg Math. J., 2010) that second Hochschild cohomology groups for the associative conformal algebra 𝐶𝑒𝑛𝑑𝑘 with coefficients in an arbitrary conformal bimodule are trivial.

Good Real Perturbations of Simple Corank One Map Germs From R3$\mathbb {R}^3$ to R3$\mathbb {R}^3$
Mathematische Nachrichten, EarlyView.ABSTRACT The existence of good real perturbations of map germs is one of the most interesting open questions in singularity theory. In this paper, we investigate this question for all simple corank one map germs from R3$\mathbb {R}^3$ to R3$\mathbb {R}^3$, we give a complete description of those that admit a good real perturbation.

PLANTS, PEOPLE, PLANET, EarlyView.Banana and plantain are vital for food security and income in West Africa, yet banana bunchy top virus (BBTV) threatens production. This study combined remote sensing, field surveys, modelling and socio‐economic analysis to assess BBTV spread and control strategies in Benin.

Systems Research and Behavioral Science, EarlyView.ABSTRACT Organisations increasingly need modelling approaches that can support sustainable development decisions across economic, environmental and social dimensions. The triple bottom line (TBL) perspective provides a useful basis for such analysis, but it also introduces modelling challenges because the relevant dimensions are often interdependent ...

Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT Rapid growth in digital finance has expanded credit access for rural smallholders, yet financial capability has not kept pace with access. Where fee structures are opaque and search is costly, this gap raises the risk of expensive borrowing in digital financial services.

Journal of the Royal Anthropological Institute, EarlyView.Contemporary artificial intelligence (AI) technologies are often presumed to be capable of revealing unmediated truths about the world, including the truths language might hold, echoing the long‐standing assertion that language's primary function is to directly translate reality.

2D Piecewise Linear Scalar Fields with Invertible Integral Lines
Computer Graphics Forum, EarlyView.Abstract Integral lines of the gradient flow are standard features in continuously differentiable scalar fields that enjoy some useful properties: They cover the domain densely, do not split, merge, or intersect, and are therefore invertible. For widely used discretizations of scalar fields, the corresponding polygonal approximations of integral lines ...

A Discrete Morse Theory for Digraphs
, 2020 Digraphs are generalizations of graphs in which each edge is assigned with a direction or two directions. In this paper, we define discrete Morse functions on digraphs, and prove that the homology of the Morse complex and the path homology are isomorphic for a transitive digraph.

Topology‐based Visual Analysis of Hydrothermal Plumes
Computer Graphics Forum, EarlyView.Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...
