I'm not quite sure if this is an appropriate question in this forum, but here is the situation.
I have just finished my graduate studies. Now, I want to explore algebraic geometry. Precisely, I am interested in the following topics:
Singular points of algebraic curves;
General methods employed...
It is generally well-known that a plane algebraic curve is a curve in ##\mathcal{CP}^{2}## given by a homogeneous polynomial equation ##f(x,y)= \sum^{N}_{i+j=0}a_{i\,j}x^{i}y^{j}=0##, where ##i## and ##j## are nonnegative integers and not all coefficients ##a_{ij}## are zero~[1].
In addition, if...
Given two algebraic curves:
##f_1(z,w)=a_0(z)+a_1(z)w+\cdots+a_n(z)w^n=0##
##f_2(z,w)=b_0(z)+b_1(z)w+\cdots+b_k(z)w^k=0##
Is there a general, numeric approach to finding where the first curve ##w_1(z)## intersects the second curve ##w_2(z)##? I know for low degree like quadratic or cubics...
I recently became interested in algebraic curves, specifically topics like parametrization and its links to differential equations. I read a number of papers but I'm looking for a good (introduction) textbook on (planar) algebraic curves that gives a solid background, not pure theoretical but...
I am reading C. G. Gibson's book: Elementary Geometry of Algebraic Curves.
I need some help with aspects of Example 1.4
The relevant text from Gibson's book is as follows:
Question 1In the above text, Gibson writes the following:
" ... ... Then a brief calculation verifies that any point $$p...
I am reading Ernst Kunz book, "Introduction to Plane Algebraic Curves"
I need help with some aspects of Kunz' Definition 1.1.
The relevant text from Kunz' book is as follows:In the above text, Kunz writes the following:
" ... ... If $$K_0 \subset K$$ is a subring and $$\Gamma = \mathscr{V}...
I am reading Ernst Kunz book, "Introduction to Plane Algebraic Curves"
I need help with Exercise 1, Chapter 1 ...
Indeed ... I am a bit overwhelmed by this problem ..
Exercise 1 reads as follows:
Hope someone can help ... ...To give a feel for the context and notation I am providing the...
I am reading the book, "Introduction to Plane Algebraic Curves" by Ernst Kunz - which the author claims gives a basic introduction to the elements of algebraic geometry.
The opening few paragraph of Kunz' text reads as follows:I am puzzled by Kunz statement:
"$$ \mathbb{A} (K) := K^2 $$...
Hi I am pretty stuck on a proof so any help would be great:
Let P and Q be two projective curves, and let p belong to both of them. Show that the intersection number of P and Q at p is equal to one iff the tangent lines to p of P and Q are distinct
NB-we have defined intersection numbers...
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...
