Fundamental tone estimates for elliptic operators in divergence form and geometric applications
Gregorio Pacelli F Bessa, Barnabe Pessoa Lima, J. Fabio Montengro +1
We establish a method for giving lower bounds for the fundamental tone of elliptic operators in divergence form in terms of the divergence of vector fields. We then apply this meth…

Properness of minimal surfaces with bounded curvature
G. Pacelli Bessa, Luquesio P. Jorge
We show that immersed minimal surfaces of with bounded curvature and proper self intersections are proper. We also show that the restriction of the immersing map t…
