WebEntanglement entropy in even dimensional conformal field theories (CFTs) contains well–known universal terms arising from the conformal anomaly. Rényi entropies are natural generalizations of the entanglement entropy t… The International Journal of Geometric Methods in Modern Physics is a peer-reviewed journal, published by World Scientific, covering mathematical physics. It was originally published bimonthly beginning in January 2004; as of 2006 it appears 8 times a year. Editorial policy for the journal specifies that "The journal publishes short communications, research and review articles devoted to the application of geometric methods (including differential geometry, algebraic geometry, glo…

WebJan 6, 2024 · 3. Department of Mathematics, Bidhan Chandra College, Asansol-4, West Bengal 713304, India. The present paper is to deliberate the class of ϵ -Kenmotsu manifolds which admits conformal η -Ricci soliton. Here, we study some special types of Ricci tensor in connection with the conformal η -Ricci soliton of ϵ -Kenmotsu manifolds. WebOct 31, 2024 · Abstract. In this article we develop a theory of contact systems with nonholonomic constraints. We obtain the dynamics from Herglotz's variational principle, by restricting the variations so that they satisfy the nonholonomic constraints. We prove that the nonholonomic dynamics can be obtained as a projection of the unconstrained … 50歲以上

WebTwo of these strategies—path integration and a cognitive map—indeed require that the explored space possess a global metric: a way in which distances can be measured uniformly and veridically across the entire space (see Box 1 for theories of how the grid pattern is utilized for self-positioning). When an animal navigates using path integration, … WebThis paper aims to be a natural continuation of our very recent research, published in [Int. J. Geom. Meth. Mod. Phys.8(4) (2011) 783–796].
