Algebraic Curves ( on understanding this proof)

In summary, the conversation discusses the contradiction of G=0 and its implication on F=0, as well as a request for a proof and a request to shrink a scanned image for better readability.

I don't get why G=0 is a contradiction. Does it imply F=0, which cannot be true since the question stated F is non constant?

Can anyone give me another proof for this first part please? As the step he made to get G would have been something I would never have thought of.

By the way problem 1.4 showed that if F(P) = 0 for all P then F = 0 when k is an infinite field.

Your scanned image is too big, at 1503 x 772 pixels. Please shrink it to no larger than about 1000 x 600 or so, so that we can read the problem without having to scroll off to the right.
Thanks

Is that better?

Better, yes, but could you shrink it a bit more? 800 x 400 would be about right.
Thanks!

800x400 now!
 

Related to Algebraic Curves ( on understanding this proof)

1. What are algebraic curves?

Algebraic curves are geometric objects that can be described by polynomial equations. They are a fundamental concept in algebraic geometry and have applications in various fields of mathematics and science.

2. How do you determine the degree of an algebraic curve?

The degree of an algebraic curve is determined by the highest power of the polynomial equation that describes it. For example, a curve described by the equation x^2 + y^2 = 1 has a degree of 2.

3. What is the relationship between algebraic curves and coordinates?

Algebraic curves can be represented by coordinates on a graph, with each point on the curve corresponding to a solution of the polynomial equation. The coordinates of the points can also be used to determine the properties of the curve, such as its degree and singularities.

4. How are algebraic curves classified?

Algebraic curves can be classified based on their degree, genus (a measure of their complexity), and other properties such as singularities and rational points. They can also be categorized into different types, such as elliptic curves, hyperelliptic curves, and rational curves.

5. What is the importance of algebraic curves in mathematics and science?

Algebraic curves have numerous applications in mathematics and science, including cryptography, coding theory, number theory, and physics. They also provide a powerful tool for studying and understanding the properties of polynomial equations and their solutions.
