Probability of connected graph on torus
Let $G = (V, E)$ be a graph on n vertices constructed in the following way:
Each vertex $v \in V$ is positioned uniform randomly in $[0, 1] × [0, 1]$.
Connect two vertices $u, v \in V$ if $d(v,u) ≤ …

Probability of each edge in K-clique [closed]
For $c \in R$ and $k \in N$, $k \geq 3$ let
$p_{k,c} := n^{\frac{−2}{k+1}}log^c(n)$.
I would like to prove that exists $c\in R$ such that every edge in the random graph $G(n,p_{k,c})$ lies in a copy …

Graph game minimum vertex degree
Consider the following graph game, given a graph $G=(V,E)$ on $n$ vertices with minimum degree $ \gg \log(n)$. Players are BR and MA (BR moves first):
BR claims an unclaimed edge from $E$, adds it t …
