    I A doubt about the multiplicity of polynomials in two variables

    Hi, andrewkirk. Thanks for commenting. I see your point. However, I did not understand your last statement. Correct me, if I am not mistaken, but by substituting ##y=-1/2## into ##P(x,y)## we will have ##P(x,-1/2) \equiv \tilde{P}(x)=50x^2+100x+50##, or, simply,##\tilde{P}(x)= 50(x+1)^2##. Based...

    I A doubt about the multiplicity of polynomials in two variables

    Let ##P(x,y)## be a multivariable polynomial equation given by $$P(x,y)=52+50x^{2}-20x(1+12y)+8y(31+61y)+(1+2y)(-120+124+488y)=0,$$ which is zero at ##q=\left(-1, -\frac{1}{2}\right)##. That is to say, $$ P(q)=P\left(-1, -\frac{1}{2}\right)=0.$$ My doubts relie on the multiplicity of this point...

    Book recommendations about singular points of algebraic curves

    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...

    I May I use set theory to define the number of solutions of polynomials?

    Hello, Mark44. I hope you are doing well! Thanks a lot for your insightful comment. That is exactly what I was thinking. However, how may I mathematically define the "reciprocal" of ##Q_n(x)##? That is to say, is there a specific notation to define the reciprocal of ##Q_n(x)##? Thanks in...

    I May I use set theory to define the number of solutions of polynomials?

    Hi, martinbn, I hope you are doing well. Thanks for commenting. It could be ##n##. However, I would prefer ##J_{n}## rather than simply ##n##.

    I May I use set theory to define the number of solutions of polynomials?

    Hi, WWGD. I hope you are doing well. Thanks for commenting. In my definition stated above, I am interested in the singular points of ##Q_{n}(x)##, which are obtained by the zeros or solutions of ##P_{n}=0##. In as much as ##(Q_{n}(x))^{-1}=P_{n}##, then I have considered...

    I May I use set theory to define the number of solutions of polynomials?

    Hi, Office_Shredder. I hope you are doing well. First, thanks for commenting. Second, I could be P since ##(Q_{n}(x))^{-1}## is ##P_{n}##. In light of the foregoing, the definition would be ##Sup\{\pi(P_{n}(x)=0):\partial P \leq n\}##. Based on the above, is there anything else that I should...

    I May I use set theory to define the number of solutions of polynomials?

    Let ##Q_{n}(x)## be the inverse of an nth-degree polynomial. Precisely, $$Q_{n}(x)=\displaystyle\frac{1}{P_{n}(x)}$$, It is of my interest to use the set notation to formally define a number, ##J_{n}## that provides the maximum number of solutions of ##Q_{n}(x)^{-1}=0##. Despite not knowing...

    Open problems and suggestions of great mathematical journals

    martinbn, Thanks for commeting! However, my question is exactly about this. Suppose that someone had undoubtedly solved an open problem in the field of algebraic geometry and mathematics. Based on your broad experience, what are the top mathematical journals to be considered first? Take, for...
