DESCRIPTION:Title: Einstein type elliptic systems.\nby Jorge de Lira (Universid
ad de Ceará) as part of Geometry Seminar\, Universidad de Granada (Spain)
\n\n\nAbstract\nWe will discuss a type of semi-linear systems of partial d
ifferential equations which are motivated by the conformal formulation of
the Einstein constraint equations coupled with realistic physical fields o
n asymptotically flat manifolds. In particular\, electromagnetic fields gi
ve rise to this kind of systems. In this context\, under suitable conditio
ns\, we prove a general existence theorem for such systems\, and\, in part
icular\, under smallness assumptions on the free parameters of the problem
\, we prove existence of far from CMC (near CMC) Yamabe positive (Yamabe n
on-positive) solutions for charged dust coupled to the Einstein equations\
, satisfying a trapped surface condition on the boundary. As a bypass\, we
prove a Helmholtz decomposition on asymptotically flat manifolds with bou
ndary\, which extends and clarifies previously known results.\n

DESCRIPTION:Title: Classification of solutions to the critical p-Laplace equations<
/a>\nby Alberto Roncoroni (University of Granada) as part of Geometry Semi
nar\, Universidad de Granada (Spain)\n\n\nAbstract\nWe consider the follow
ing critical $p$-Laplace equation: \n\n$(1)\\qquad \\Delta_p u+u^{p^{\\ast
}-1}=0 \\quad \\text{ in $\\mathbb{R}^n$}\, $\n\nwith $n \\geq 2$ and $1 <
p < n$. Equation \\eqref{p-Laplace} has been largely studied in the PDE's
and geometric analysis' communities\, since extremals of Sobolev inequali
ty solve \\eqref{p-Laplace} and\, for $p=2$\, the equation is related to t
he Yamabe's problem. In particular\, it has been recently shown\, exploiti
ng the moving planes method\, that positive solutions to (1) such that \n$
u\\in L^{p^\\ast}(\\mathbb{R}^n)$ and $\\nabla u\\in L^p(\\mathbb{R}^n)$ c
an be completely classified. In the talk we will consider the anisotropic
critical $p$-Laplace equation in convex cones of $\\mathbb{R}^n$. Since th
e moving plane method strongly relies on the symmetries of the equation an
d of the domain\, in the talk a different approach to this problem will be
presented. In particular this approach gives a complete classification of
the solutions in an anisotropic setting. More precisely\, we characterize
solutions to the critical $p$-Laplace equation induced by a smooth norm i
nside any convex cone of $\\mathbb{R}^n$.\n%which allows us to give a comp
lete classification of the solutions in an anisotropic setting as well as
to a suitable generalization of the problem in convex cones\n\nThis is a j

first non-trivial examples of embedded constant mean curvature tori in $\\

DESCRIPTION:Title: Schwarz-Pick lemma for harmonic maps which are conformal at a po
int\nby Franc Forstnerič (University of Ljubljana) as part of Geometr
y Seminar\, Universidad de Granada (Spain)\n\n\nAbstract\nWe obtain a shar
p estimate on the norm of the differential of a harmonic map from the unit
disc ${\\mathbb D}$ in $\\C$ to the unit ball ${\\mathbb B}^n$ in $\\R^n$
\, $n\\ge 2$\, at any point where the map is conformal. In dimension $n=2$
this generalizes the classical Schwarz-Pick lemma to harmonic maps $\\mat
hbb D\\to\\mathbb D$ which are conformal only at the reference point. In d
imensions $n\\ge 3$ it gives the optimal Schwarz-Pick lemma for conformal
minimal discs $\\mathbb D\\to {\\mathbb B}^n$. Let ${\\mathcal M}$ denote
the restriction of the Bergman metric on the complex $n$-ball to the real
$n$-ball ${\\mathbb B}^n$. We show that conformal harmonic immersions $M \
\to ({\\mathbb B}^n\,{\\mathcal M})$ from any hyperbolic open Riemann surf
ace $M$ with its natural Poincar\\'e metric are distance-decreasing\, and
the isometries are precisely the conformal embeddings of $\\mathbb D$ onto
affine discs in ${\\mathbb B}^n$. (Joint work with David Kalaj.)\n

DESCRIPTION:Title: On non-compact free boundary minimal hypersurfaces in the Rieman
nian Schwarzschild spaces\nby Ezequiel Barbosa (Universidad de Granada
) as part of Geometry Seminar\, Universidad de Granada (Spain)\n\n\nAbstra
ct\nWe will show that\, in contrast with the 3-dimensional case\, the Mors
e index of a free boundary rotationally symmetric totally geodesic hypersu
rface of the $n$-dimensional Riemannnian Schwarzschild space with respect
to variations that are tangential along the horizon is zero\, for $n\\geq4
$. Moreover\, we will show that there exist non-compact free boundary mini
mal hypersurfaces which are not totally geodesic\, $n\\geq 8$\, with Morse
index equal to 0. Also\, for $n\\geq4$\, there exist infinitely many non-
compact free boundary minimal hypersurfaces\, which are not congruent to
each other\, with infinite Morse index. Finally\, we will discuss the dens
ity at infinity of a free boundary minimal hypersurface with respect to a
minimal cone constructed over a minimal hypersurface of the unit Euclidean
sphere. We obtain a lower bound for the density in terms of the area of t
he boundary of the hypersurface and the area of the minimal hypersurface i
n the unit sphere. This lower bound is optimal in the sense that only mini
mal cones achieve it.\n

, Moruz (Al.I. Cuza University of Iasi) as part of Geometry Seminar\, Univ
ersidad de Granada (Spain)\n\n\nAbstract\nH. Anciaux and K. Panagiotidou [
1] initiated the study of non-degenerate real hypersurfaces in non-flat in
definite complex space forms in 2015. Next\, in 2019 M. Kimura and M. Orte
ga [2] further developed their ideas\, with a focus on Hopf real hypersurf
aces in the indefinite complex projective space $\\mathbb CP^n_p$. In this
work we are interested in the study of non-degenerate ruled real hypersur
faces in $\\mathbb CP^n_p$. We first define such hypersurfaces\, then give
basic characterizations. We also construct their parameterization. They a
re described as follows. Given a regular curve $\\alpha$ in $\\mathbb CP^n
_p$\, then the family of the complete\, connected\, complex $(n − 1)$-di
mensional totally geodesic submanifolds orthogonal to $\\alpha'$ and $J\\a
lpha'$\, where $J$ is the complex structure\, generates a ruled real hyper
surface. This representation agrees with the one given by M. Lohnherr and
H. Reckziegel in the Riemannian case [3]. Further insights are given into
the cases when the ruled real hypersurfaces are minimal or have constant s
ectional curvatures. The present results are part of a joint work together

DESCRIPTION:Title: Mean Curvature Flow with Boundary\nby Brian White (Stanford
University) as part of Geometry Seminar\, Universidad de Granada (Spain)\
n\n\nAbstract\nAlmost all of the extensive research on mean curvature flow
has been for surfaces without boundary. However\, it is interesting and n
atural to consider MCF for surfaces with boundary. In this talk\, I will d
escribe a useful weak formulation of such flows that gives existence for a
ll time with arbitrary initial data. Furthermore\, under rather mild hypot
heses on the initial surface\, the moving surface remains forever smooth a
t the boundary\, even after singularities may have formed in the interior.
On the other hand\, if one relaxes those hypotheses\, then interesting bo
undary singularities can occur.\n

DESCRIPTION:Title: Curvature of minimal graphs\nby David Kalaj (University of
Montenegro) as part of Geometry Seminar\, Universidad de Granada (Spain)\n
\n\nAbstract\nWe consider the Gaussian curvature conjecture of a minimal g
raph $S$ over the unit disk. First of all we reduce the general conjecture
to the estimating the Gaussian curvature of some Scherk's type minimal su
rfaces over a quadrilateral inscribed in the unit disk containing the or
igin inside.\nAs an application we improve so far the obtained upper estim
ates of Gaussian curvature at the point above the center. Further we obt
ain an optimal estimate of the Gaussian curvature at the point $\\mathbf{w
}$ over the center of the disk\, provided $\\mathbf{w}$ satisfies certain
"symmetric" conditions. The result extends a classical result of Finn and
Osserman in 1964. In order to do so\, we construct a certain family $S^t$\
, $t\\in[t_\\circ\, \\pi/2]$ of Scherk's type minimal graphs over the isos
celes trapezoid inscribed in the unit disk. Then we compare the Gaussian c
urvature of the graph $S$ with that of $S^t$ at the point $\\mathbf{w}$ ov
er the center of the disk.\n
