Induced scattering limits on fast radio bursts from stellar coronae
Yuri Lyubarsky, Sofiya Ostrovska
The origin of fast radio bursts remains a puzzle. Suggestions have been made that they are produced within the Earth atmosphere, in stellar coronae, in other galaxies or at cosmolo…
Nonexistence of embeddings with uniformly bounded distortions of Laakso graphs into diamond graphs
Sofiya Ostrovska, Mikhail I. Ostrovskii
Diamond graphs and Laakso graphs are important examples in the theory of metric embeddings. Many results for these families of graphs are similar to each other. In this connection,…
Distortion of embeddings of binary trees into diamond graphs
Siu Lam Leung, Sarah Nelson, Sofiya Ostrovska +1
Diamond graphs and binary trees are important examples in the theory of metric embeddings and also in the theory of metric characterizations of Banach spaces. Some results for thes…
Distortion in the finite determination result for embeddings of locally finite metric spaces into Banach spaces
Sofiya Ostrovska, Mikhail I. Ostrovskii
Given a Banach space and a real number , we write: (1) if, for any locally finite metric space , all finite subsets of which admit bilipschitz embeddings…
