On the center of distances of finite ultrametric spaces

Oleksiy Dovgoshey, Olga Rovenska

The center of distances of a metric space $(X, d)$ is the set $C (X)$ of all $t \in R^{+}$ for which the equation $d (x, p) = t$ has a solution for each $p \in X$ . We prove the inequ…

A Joint Analysis of Strong Lensing and Type Ia Supernovae to Determine the Hubble Constant

L. R. Colaço, R. F. L. Holanda, Z. C. Santana +1

We present a cosmological model-independent determination of the Hubble constant, $H_{0}$ , by combining time-delay measurements from seven TDCOSMO systems, Einstein radius measuremen…
