Cerrado is the second largest biome in South America and accounted for the second largest contribution to carbon emissions in Brazil for the last 10 years, mainly due to land-use changes. It comprises approximately 2 million km2 and is divided into 2

Given an arbitrary $$C^\infty $$ Riemannian manifold $$M^n$$ , we consider the problem of introducing and constructing minimal hypersurfaces in $$M\times \mathbb {R}$$ which have the same fundamental properties of the standard helicoids and catenoids

In this note we present a method for constructing constant mean curvature on surfaces in hyperbolic 3-space in terms of holomorphic data first introduced in Bianchi's Lezioni di Geometria Differenziale of 1927, therefore predating by many years the m

The 1d family of Poncelet polygons interscribed between two circles is known as the Bicentric family. Using elliptic functions and Liouville's theorem, we show (i) that this family has invariant sum of internal angle cosines and (ii) that the pedal p

We introduce a class of surfaces in Euclidean space motivated by a problem posed by Elie Cartan. This class furnishes what seems to be the first examples of pairs of non-congruent surfaces in Euclidean space such that, under a diffeomorphism $$\Phi $

International audience; We analyze a case of plagiarism that appears in a work published in 1928 by Paul Appell (1855–1930) in the collection Mémorial des sciences mathématiques. Appell's memoir entitled Le problème géométrique des déblais et
