- Propositional Logic Help with First Order Logicby John Cyphers on April 18, 2024 at 9:58 pm

- Existence of Nash Equilibrium in a Game with Mixed Strategy Spacesby graphtheory123 on April 18, 2024 at 9:54 pm
I am considering formulating an applied research problem as a simultaneous zero-sum game with two players. The first player's set of actions is an infinite and compact subset of $\mathbb{R}^n$, while the second player has a finite number of actions. For a specific action $s_2$ chosen by Player 2, I am aware of the result stating that if the set of choices for each player were compact and the payoff function were continuous in the strategies of all players, then a (mixed) Nash Equilibrium would exist. However, since Player 2's actions are discrete, this result does not apply directly to my case. Are there any results that might guarantee the existence of a Nash Equilibrium under perhaps a few additional conditions for problems like mine? I have struggled to find relevant information on this topic in my searches.
- Find the value of $9(x^3+y^3)$by MathStackexchangeIsNotSoBad on April 18, 2024 at 9:49 pm
If $$\ln\left(x^3+\frac{y^3}{3}+\frac19\right)=\ln x+\ln y$$ then find the value of $9(x^3+y^3)$ I am stuck after doing $x^3+\frac{y^3}{3}+\frac19=xy$ I am not able to think what to do after this. I highly think that is expression is factorable but I am not able to do that. Any help is greatly appreciated.
- Reference request? Lévy's continuity theoremby Iván P. on April 18, 2024 at 9:48 pm
I am trying to understand a proof that involves constructing a measure $\mu$ as a weak limit of measures $\mu_k$. The autor concludes the weak convergence as a consequence of Lévy's continuity theorem. I've looked this theorem up and it is stated for probability measures. The thing is, I am not seeing how the measures $\mu_k$ involved are of Probability. But this is not what I am here to ask. I suspect that this might not even be the case, because after the measure $\mu$ is constructed, the author goes out of his way to prove that $\mu$ is not the zero measure, which should be obvious if the measure was of Probability, as the theorem guarantees. This leads me to believe that there is some version of Levy's theorem for non-probability measures that I haven't been able to find. Is this the case? If so where could I find it?
- How do you know when level curves are straight?by user326210 on April 18, 2024 at 9:39 pm
I have a smooth function $F(x,y)$ which sends an open disc $D\subset \mathbb{R}^2$ in the plane to $\mathbb{R}$. I would like to know how to compute whether the level curves of $F$ are all each (a subset of) a line. For example, $F$ might be a function like $ax+by+c$ whose the level curves are all parallel lines. Or $F$ might be a function with "radial" contours, e.g. $F(x,y)$ is the slope of the line between $(x,y)$ and the origin, and $D$ is a disc in the first quadrant. So far, it seems to me that: There are only two basic ways the contours can all be lines --- the radial case, and the parallel lines case. This is because the contours cannot intersect If you have a functional form for $F$, it should be possible to perform a test, possibly involving logarithms of ratios of derivatives, to determine whether the level curves are all straight. I haven't been able to devise such a test yet, however. One way of looking at it is to pick a point $p\in D$ and let $\gamma_p:\mathbb{R}\rightarrow \mathbb{R}^2$ be the line that passes through $p$ parallel to the level curve of $F$. Then the claim is roughly that for all $p$, $F\circ \gamma_p$ is constant, i.e. its derivative vanishes.
