comment Is such a function in $L^2$?
Never mind... That was a misprint, a typo (the correct version being "$t\mapsto \langle A(t,x^*(t)), x(t) - x^*(t)\rangle$ is an $L^{\bf \color{red} 1}([0,T];\mathbb{R})$ function"). What amazes me at the moment is that the same typo can be found on (at least) three different papers from the same authors.

comment Integrating $\int_{1}^{\sqrt{3}} \sqrt{1+\frac{1}{t}}dt$
Try to substitute $u=\sqrt{1+\frac{1}{t}}$...

comment First Order differential equation (Schaefer model)
What have you tried so far? A qualitative study of the solutions is quite easy, I guess... P.S.: Are $E$, $K$ and $r$ positive constants?

comment Let $(a_n)_{n\geq 1}$ be a sequence of integers defined by $a_1=1, a_2=2$, and for each $n\geq 1$, $a_{n+2} =a_{n+1} +3a_n$.
