On quintic surfaces of general type [PDF]
Transactions 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.

Surfaces of general type with q = 2 are rigidified [PDF]
Communications in Contemporary Mathematics, 2018 Let [Formula: see text] be a minimal smooth projective surface of general type with irregularity [Formula: see text]. We show that, if [Formula: see text] has a nontrivial holomorphic automorphism acting trivially on the cohomology with rational coefficients, then it is a surface isogenous to a product.

CANONICALLY FIBERED SURFACES OF GENERAL TYPE [PDF]
Journal 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 $g\geqslant 4$

Torelli problem for surfaces of general type [PDF]
Torelli problem for surfaces of general typeThis article is a report of the present situation of the Torelli type problem for surfaces of general type. This article also contains new results on the surfaces with p_g = 1, c^2_1 = 2 and π_1 = Z/2Z.

The Arithmetic and Geometry of a Class of Algebraic Surfaces of General Type and Geometric Genus One [PDF]
, 2010 We study of a class of algebraic surfaces of general type and geometric genus one, with a view toward arithmetic results. These surfaces, called CC surfaces here, have been classified over the complex numbers by Catanese and Ciliberto.

Uniruled surfaces of general type [PDF]
Mathematische Zeitschrift, 2007 We give a systematic construction of uniruled surfaces in positive characteristic. Using this construction, we find surfaces of general type with non-trivial vector fields, surfaces with arbitrarily non-reduced Picard schemes as well as surfaces with inseparable canonical maps.

Ruled algebraic surfaces with a main frame from three superellipses
Structural Mechanics of Engineering Constructions and Buildings, 2022 An opportunity of conversion of algebraic surfaces with a main frame from three superellipses of general type into ruled surfaces of several views is shown. It is necessary to take one, two, or all of three superellipses in the form of a rhombus, i.e. it

Lines of Curvature for Log Aesthetic Surfaces Characteristics Investigation
Mathematics, 2021 Lines of curvatures (LoCs) are curves on a surface that are derived from the first and second fundamental forms, and have been used for shaping various types of surface. In this paper, we investigated the LoCs of two types of log aesthetic (LA) surfaces;
