Systems of non-linear algebraic equations
|
| |
Dear Newsgroup: Systems of algebraic equations like the following two equations in unknowns {x,y}: Eq1: m3*x^3+m1*x+n2*y^2+n1*y =r1; Eq2: a3*x^3 +a2*x^2+b2*y^2+b1*y=r2; Can also be handled by Riccati equations as its sole developments. Normally we will parameterize it and handle its systems of differential equations via Riccati.... more »

A Letter of Einstein 2008
 
|
| |
Dear Sirs, my name is Albert Einstein. I was told that some idiot named Mehran Basti reads my old private letters and shows them to the public. I am writing to you this open letter to state without doubt that this moron, Mehran Basti, is the most stupid and ignorant person on our planet Earth. This cretin writes to me daily here at Princeton stating that... more »

The future math newsgroup
|
| |
Dear Newsgroup: Similar to many other fields like relativity, NEW EXACT MATH will have its own newsgroup in the future. Like newsgroup sci.physics.relativity, we will also have sci.math.new exact math. This is because the field is a universe of its own and practically we need to start off all aspects of problem solving from the scratch.... more »

Tracing the NG abuser
|
| |
Dear Newsgroup: I have written a letter to the Internet partners and I am following up with their recommendation (sent an email to the abuse department). The person in question is in Germany. Here is their letter, what is the situation? Any lessons for the Usenet? Hi Mehran, If you look again at the bottom you will see the line:... more »

Nash equilibria and symbolic computation
|
| |
Does anyone know how much has been achieved or attempted in computing Nash equilibria symbolically? I have been reading this paper by Ruchira Datta: Finding All Nash Equilibria of a Finite Game Using Polynomial Algebra. [link] The point is to solve a system of polynomial equations. In the paper (p. 33) she has the equations for the case of three players with two pure strategies, and solves them with Singular (let's call this the 3-2 case). How about the 4-2 case, or the 3-3 case? Again, I want fully symbolic solutions, not numerical computing.... more »

Time for revolutionary decisions
|
| |
Dear Newsgroup: My mind is gone. My head is out of control. Surgeons said my only hope at this stage is brain transplant. Now I have to wait for a donor. Main candidates are those two: a retarded pidgeon and a dead rat. Yet surgeons are afraid of overloading my head with too much brain. Maybe an amoeba is more than enough for me and my NEW EXACT MATH.... more »

Another Riccati from a different class polynomial
|
| |
Dear Newsgroup: Please find enclosed a PDF file of a Riccati differential equation in a normalized form. [link] This Riccati has been generated from another different class polynomial of degree 31. Since the polynomial has been solved (without integration), thus we... more »
