Dec 10, 2012 at 11:53 comment added user16517 My guess is that a more meaningful inequality would have $C$ depend only on the $t_i$, but that's for you to decide.
Dec 10, 2012 at 11:52 comment added user16517 Suppose Delio's comments were imposed, i.e. you look only at $a_i \geq 0$ (I see you have $C>0$ now.). As it is now you've "given too much" to be a meaningful inequality, because you've given the $a_i , b_i,$ and $t_i$. This means that the right hand side is fully determined, as is everything on the left hand side except for C. Also both sides are nonnegative. Thus, the question reduces to asking if the left hand side is nonzero, whether there is a positive number $C \leq $ to the quotient of two positive numbers, which is always a positive number so yes.

Dec 10, 2012 at 11:09 comment added Delio Mugnolo Your statement cannot be true. You need at very least to ask whether there is $C>0$ such that [...] and to impose that also $a_i>0$ (otherwise you could simply obtain the reverse inequality simply by flipping the sign of $a_i$).
