Asymptotics and zero behaviour of geometric polynomials

M. Bello-Hernández, M. Benito, Ó. Ciaurri +1

We obtain some results on the asymptotic behaviour of Geometric polynomials in both the complex plane minus $[- 1, 0]$ and the interval $(- 1, 0)$ . We also find the distance of consecu…

Engel CR submanifolds of $C^{3}$

Eduardo Fernández, Álvaro del Pino, Wei Zhou

We give a sufficient condition for an $S^{1}$ -bundle over a $3$ -manifold to admit an immersion (or embedding) into $C^{3}$ so that its complex tangencies define an En…

Grasper families of spheres in $S^{2} \times D^{2}$ and barbell diffeomorphisms of $S^{1} \times S^{2} \times I$

Eduardo Fernández, David T. Gay, Daniel Hartman +1

We show that the fundamental group of framed circles in $S^{1} \times D^{3}$ injects into the fundamental group of framed spheres in $S^{2} \times D^{2}$ , so that the cokernel is the fundam…
