On quintic surfaces of general type [PDF]

open access: yesTransactions of the American Mathematical Society, 1986
The study of quintic surfaces is of special interest because 5 5 is the lowest degree of surfaces of general type.

CANONICALLY FIBERED SURFACES OF GENERAL TYPE [PDF]

open access: yesJournal of the Institute of Mathematics of Jussieu, 2018
In this paper, we construct the first examples of complex surfaces of general type with arbitrarily large geometric genus whose canonical maps induce non-hyperelliptic fibrations of genus $g=4$, and on the other hand, we prove that there is no complex surface of general type whose canonical map induces a hyperelliptic fibrations of genus $g\geqslant 4$

surface remeshing in arbitrary codimensions [PDF]

open access: yes, 2006
We present a method for remeshing surfaces that is both general and efficient. Existing efficient methods are restrictive in the type of remeshings they produce, while methods that are able to produce general types of remeshings are generally based on ...

Syzygies of surfaces of general type [PDF]

open access: yesGeometriae Dedicata, 2012
We prove new results on projective normality, normal presentation and higher syzygies for a surface of general type $X$ embedded by adjoint line bundles $L_r = K + rB$, where $B$ is a base point free, ample line bundle. Our main results determine the $r$ for which $L_r$ has $N_p$ property.

On the Degree of the Canonical Map of a Surface of General Type

open access: yes, 2023
Let X be a minimal complex surface of general type such that its image via the canonical map is a surface; we denote by d the degree of the canonical map. In this expository work, first of all we recall the known possibilities for the canonical image and for d when the canonical map is not birational, which are quite a few, and then we consider the ...

Hybrid organic/inorganic nanotubes of imogolite type [PDF]

open access: yes, 2012
The aim of the present PhD project is to describe the developments obtained in imogolite research field, concerning the synthesis and characterization of two new modified imogolite nanotubes, either by direct or post-synthesis reactions, as compared to ...

A new simple topo-climatic model to predict surface displacement in paraglacial and periglacial mountains of the European Alps: The importance of ground heating index and floristic components as ecological indicators

open access: yesEcological Indicators, 2021
Landscape evolution is occurring at rapid rates in alpine areas in response to recent climate warming, also due to the susceptibility and the heterogeneity of these environments. Here we present a prediction model of surface displacements that takes into

Diffusion of Cd and Te adatoms on CdTe(111) surfaces: A computational study using density functional theory

open access: yesAIP Advances, 2015
CdTe is one of the most promising semiconductor for thin-film based solar cells. Here we report a computational study of Cd and Te adatom diffusion on the CdTe (111) A-type (Cd terminated) and B-type (Te terminated) surfaces and their migration paths ...
