Generalized Developable Cubic Trigonometric Bézier Surfaces
Mathematics, 2021 This paper introduces a new approach for the fabrication of generalized developable cubic trigonometric Bézier (GDCT-Bézier) surfaces with shape parameters to address the fundamental issue of local surface shape adjustment.

Relaxation of Some Confusions about Confounders
Entropy, 2021 This work is about observational causal discovery for deterministic and stochastic dynamic systems. We explore what additional knowledge can be gained by the usage of standard conditional independence tests and if the interacting systems are located in a

Hosoya properties of the commuting graph associated with the group of symmetries
Main Group Metal Chemistry, 2021 A vast amount of information about distance based graph invariants is contained in the Hosoya polynomial. Such an information is helpful to determine well-known distance based molecular descriptors.

Evolutionary dynamics on a regular networked structured and unstructured multi‐population
International Journal of Robust and Nonlinear Control, EarlyView., 2023 Abstract In this paper, we study collective decision‐making in a multi‐population framework, where groups of individuals represent whole populations that interact by means of a regular network. Each group consists of a number of players and every player can choose between two options.

A Geodesic-Based Riemannian Gradient Approach to Averaging on the Lorentz Group
Entropy, 2017 In this paper, we propose an efficient algorithm to solve the averaging problem on the Lorentz group O ( n , k ) . Firstly, we introduce the geometric structures of O ( n , k ) endowed with a Riemannian metric where geodesic could be ...

Curve shortening by short rulers
ESAIM: Proceedings and Surveys, 2014 The aim is to construct a straight line between the two endpoints of a rectifiable curve using only a ruler, which is too short to connect them directly.

Geodesic diagrams, gravitational interactions & OPE structures [PDF]
Journal of High Energy Physics, 2017 We give a systematic procedure to evaluate conformal partial waves involving symmetric tensors for an arbitrary CFTd using geodesic Witten diagrams in AdSd+1. Using this procedure we discuss how to draw a line between the tensor structures in the CFT and
