Apr 10, 2014 at 16:45 | comment | added | BPN | I mean asymptotically, of course. When I say $d$ fixed, I mean for large $d$ and infinitely many $n$ (number of vertices) for that $d$, i.e., $d \to \infty$ and for each $d$ in that sequence, an infinite family of graphs on a larger and larger number of vertices of average degree about $d$. Does that clarify what I'm asking for? | |
Apr 10, 2014 at 16:12 | comment | added | Dr J | If $d$ is a positive integer, then a graph with average degree $d$ must actually contain a subgraph with minimum degree at least $\lfloor\frac{d}{2}\rfloor+1>\frac{d}{2}$, so when you say that the constant $\frac{1}{2}$ cannot be improved, you mean asymptotically as $d\to\infty$, right ? But then in the second part of your post you seem to consider $d$ as being fixed. Could you clarify ? | |
