On Separation of Variables for Symmetric Spaces of Rank1
Alexey Bolsinov, Holger R. Dullin, Vladimir. S. Matveev +1
We study existence and nonexistence of diagonal and separating coordinates for Riemannian symmetric spaces of rank 1. We generalize the results of Gauduchon and Moroianu, 2020, by…

A sharp refinement of a result of Alon, Ben-Shimon and Krivelevich on bipartite graph vertex sequences
Grant Cairns, Stacey Mendan, Yuri Nikolayevsky
We give a sharp refinement of a result of Alon, Ben-Shimon and Krivelevich. This gives a sufficient condition for a finite sequence of positive integers to be the vertex degree lis…

A sharp refinement of a result of Zverovich--Zverovich
Grant Cairns, Stacey Mendan, Yuri Nikolayevsky
For a finite sequence of positive integers to be the degree sequence of a finite graph, Zverovich and Zverovich gave a sufficient condition involving only the length of the sequenc…
