Algebraic quartic surfaces are a classical subject of algebraic geometry and the study of their rich properties has been developed in research papers and books since the XIX century. Many di erent classi cations for several classes of quartic surfaces where introduced (for instance, see [11], the books [6] and [4];Author: Mauro Carlo Beltrametti, Alessandro Logar, Maria Laura Torrente. We compute the Jacobian of these equations and derive the algebraic equation of the surface of points in C + (P 2) for which this Jacobian is singular, called the singularity surface of the manipulator. For the general planar platform manipulator this surface is a quartic surface Cited by:

In mathematics, a quadric or quadric surface (quadric hypersurface in higher dimensions), is a generalization of conic sections (ellipses, parabolas, and hyperbolas).It is a hypersurface (of dimension D) in a (D + 1)-dimensional space, and it is defined as the zero set of an irreducible polynomial of degree two in D + 1 variables (D = 1 in the case of conic sections). This results in 16 singularities, at the 2-torsion points of A. The minimal resolution of this quotient is a genus 3 K3 surface. A non-singular degree 4 surface in P3 is a genus 3 K3 surface. The intersection of a quadric and a cubic in P4 gives genus 4 K3 surfaces.

A quartic surface without singular curves may have at most 16 singular points. Fact Let V be a normal quartic surface. a) Then, not more than three singular points on V may be collinear. b) If three singular points on V are collinear then the line connecting them lies on V. Proof. b) Otherwise, this line would meet V in each of the three File Size: KB. Given a quartic surface possessing a singular conic and four noncoplanar isolated singular points, previously known to bear two families of conic curves, (i) along any conic from either family the surface is tangent to a quadric cone whose vertex lies on a line through one of the pairs of singular points, and (ii) the families of conics Cited by:

Excerpt from Quartic Surfaces: With Singular Points A surface which would naturally take a prominent position in such a book is the Kummer surface, together with its special forms, the tetrahedroid and the wave surface, but the admirable work written by the late R.

The theory of surfaces has reached a certain stage of completeness and major efforts concentrate on solving concrete questions rather than further developing the formal theory.

Many of these questions are touched on in this classic volume: such as the classification of quartic surfaces, the description of moduli spaces for abelian surfaces, and the automorphism group of a Kummer surface.

Regarding singular quartic surfaces in $\mathbb C \mathbb{P}^3$, the classical reference is Jessop's book Quartic surfaces with singular points (). An electronic copy of the book is freely available for legal download here.

complex K3 quartic surface with 52 lines and 2 singular points of type A1, whose equation is not known. Non-K3 complex quartic surfaces have been studied by González Alonso and Rams [7]. If they are not ruled by lines, they can contain at most 48 lines.

On the computation of singular plane curves and quartic surfaces In this section we compute equa tions of singular quartic surfaces Enumeration of combinations of rational double points Author: Carlos Rito.

The classiﬁcation of singular points of real quartic curves is originally due to D.A. Gudkov [2,3,4,5]. He determined the individual types of singular points, as well as all possible sets of singular points that real quartic curves can have.

In this paper, we will derive the thirteen individual types of singular points for.

On the other hand, a projective quartic surface is a surface in projective space P 3 of the same form, but now f is a homogeneous polynomial of 4 variables of degree 4, so for example f(x,y,z,w) = x 4 + y 4 + xyzw + z 2 w 2 − w 4.

Ruled quartic surfaces, models and classification The classiﬁcation of ruled quartic surfaces in the book of W.L. Edge [7] is identical with the one of Cremona.

this singular point. Construction. For any quadric line complex, the lines of the complex in a plane envelop a quadric in the plane. A Plücker surface depends on the choice of a quadric line complex and a line, and consists of points of the quadrics associated to the planes through the chosen line.The paper [5] contains a complete classification of smooth complex quartic surfaces with many lines.

Finally, lines on complex quartics with singular points are considered in [20], [8]. The Fermat surface 4,6, 8, 12,20 this is the best known example of a surface .Lines on quartic surfaces. singular spatial quartic surface is 64 (respectively, 56).
