Analytic extension of Jorge-Meeks type maximal surfaces in Lorentz-Minkowski 3-space

Shoichi Fujimori, Yu Kawakami, Masatoshi Kokubu +3

The Jorge-Meeks $n$ -noid ( $n \geq 2$ ) is a complete minimal surface of genus zero with $n$ catenoidal ends in the Euclidean 3-space $R^{3}$ , which has $(2 π / n)$ -rotation sy…

Group rings of countable non-abelian locally free groups are primitive

Tsunekazu Nishinaka

We prove that every group ring of a non-abelian locally free group which is the union of an ascending sequence of free groups is primitive. In particular, every group ring of a cou…
