PLoS Computational Biology, 2022 When two streams of pedestrians cross at an angle, striped patterns spontaneously emerge as a result of local pedestrian interactions. This clear case of self-organized pattern formation remains to be elucidated. In counterflows, with a crossing angle of

On Bisectors in Quaternionic Hyperbolic Space
Bulletin of the Brazilian Mathematical Society, New Series, 2023 In this paper, we study a problem related to geometry of bisectors in quaternionic hyperbolic geometry. We develop some of the basic theory of bisectors in quaternionic hyperbolic space $H^n_Q$. In particular, we show that quaternionic bisectors enjoy various decompositions by totally geodesic submanifolds of $H^n_Q$.

A new method for global optimization [PDF]
ESAIM: Proceedings and Surveys, 2021 This paper presents a new method for global optimization. We use exact quadratic regularization for the transformation of the multimodal problems to a problem of a maximum norm vector on a convex set.

On Bisectors for Convex Distance Functions [PDF]
2011 Eighth International Symposium on Voronoi Diagrams in Science and Engineering, 2011 It is well known that the construction of Voronoi diagrams is based on the notion of \emph{bisector} of two given oints. Already in nor med linear spaces, bisectors have a complicated structure and can, for many classes of norms, only be described with the help of topological methods.

On the insolubility of one drawing problem II
Lietuvos Matematikos Rinkinys, 2016 It is shown in the article that, in general, it is not possible to draw a triangle using a compass and a straightedge given an angle and a bisector and a median drawn from the vertices of another different angles.
