A Normal Form for Cubic Surfaces

نویسنده

چکیده

We consider cubic surfaces with rational coefficients that contain a rational point and satisfy a certain condition regarding their coefficients. Each such cubic surface is shown to be birationally equivalent to a surface of the form z2 = f(x, y), where f(x, y) is a polynomial of degree at most 4. Our method is similar to that which Tate and Silverman used in [2] to put cubic curves into Weierstrass form. Mathematics Subject Classification: 14J25, 14E05

Automorphism Groups on Normal Singular Cubic Surfaces with No Parameters

The classification of normal singular cubic surfaces in P3 over a complex number field C was given by J. W. Bruce and C. T. C. Wall. In this paper, first we prove their results by a different way, second we provide normal forms of normal singular cubic surfaces according to the type of singularities, and finally we determine automorphism groups on normal singular cubic surfaces with no parameters.

Discrete Affine Minimal Surfaces with Indefinite Metric

Inspired by the Weierstrass representation of smooth affine minimal surfaces with indefinite metric, we propose a constructive process producing a large class of discrete surfaces that we call discrete affine minimal surfaces. We show that they are critical points of an affine area functional defined on the space of quadrangular discrete surfaces. The construction makes use of asymptotic coordi...

تعیین گستره دمایی کانه زایی در معدن مس چهار گنبد با استفاده از ریخت شناسی بلورهای پیریت

Chahar-Gonbad copper mine, in Kerman province, has mainly formed as veins with low reserves and medium grade. Mineralization is mainly occured as chalcopyrite, pyrite, rare galena and sphalerite. Sericitic, argillic and propylitic alterations have been identified in this are deposit. These alteration occurod in the thermal range of about 350 C. In this research, the morphology of pyrite c...

Homology of Singular Cubic Surfaces in P(3,C)

An 1871 paper by Diekmann contains all the information needed to compute the integer singular homology for all classes of not ruled singular cubic surfaces. Three linearly independent quadrics in projective threespace deene a cubic Cremona transformation that associates to any point x the intersection of the polar planes of x with respect to the three quadrics. That intersection is a point y ex...

Asymptotic Nets and Discrete Affine Surfaces with Indefinite Metric

Asymptotic net is an important concept in discrete differential geometry. In this paper, we show that we can associate affine discrete geometric concepts to an arbitrary non-degenerate asymptotic net. These concepts include discrete affine area, mean curvature, normal and co-normal vector fields and cubic form, and they are related by structural and compatibility equations. We consider also the...
