On the asymptotic Plateau problem for area minimizing surfaces in $${\mathbb {E}}(-1,\tau )$$

Autor: Patrícia Klaser, Álvaro K. Ramos, Ana Menezes

Publikováno v: Annals of Global Analysis and Geometry. 58:1-17

We prove some existence and non-existence results for complete area minimizing surfaces in the homogeneous space $\mathbb{E}(-1,\tau)$. As one of our main results, we present sufficient conditions for a curve $\Gamma$ in $\partial_{\infty} \mathbb{E}

The emergence of SARS-CoV-2 P.1 lineage coincided with a surge in hospitalisations in the North region of Brazil. In the South region’s Rio Grande do Sul state, severe COVID-19 case numbers rose 3.8 fold in February 2021. During that month, at a CO

The emergence SARS-CoV-2 P.1 lineage has been coincidental with a rapid growth in hospitalization in the northern region of Brazil. An exponential growth of severe COVID-19 occurred in Rio Grande do Sul state, Southern Brazil in February-2021. Whole-

A nonexistence result for CMC surfaces in hyperbolic 3-manifolds

Autor: William H. Meeks, Álvaro K. Ramos

We prove that a complete hyperbolic 3-manifold of finite volume does not admit a properly embedded noncompact surface of finite topology with constant mean curvature greater than or equal to 1.

Properly immersed surfaces in hyperbolic $3$-manifolds

Autor: Álvaro K. Ramos, William H. Meeks

Publikováno v: J. Differential Geom. 112, no. 2 (2019), 233-261

We study complete finite topology immersed surfaces $\Sigma$ in complete Riemannian $3$-manifolds $N$ with sectional curvature $K_N\leq -a^2\leq 0$, such that the absolute mean curvature function of $\Sigma$ is bounded from above by $a$ and its injec
