comment Give a context-free grammar to generate the following language $L = \{ a^ib^jc^k \space|\space 0 \leq i \leq j \leq i + k \}$
Currently two of your exponents are i. I assume one of them should be a j.

comment Showing this integral from complex analysis is an integer without residues
I see now that I made a mistake in my original post. I'll correct it.

comment A proof (?) of a Cauchy Integral Theorem type claim
I forgot to ask a question. The question is, have I erred? I would guess this isn't at all the proof which is expected, and I haven't had much experience using LDCT "in the wild" before, so I am, as usual, a bit uncertain.

Thanks for pointing that out.

comment Convergence of a power series in the complex plane — does this argument work?
Oh, I see. So, to get a derivation which is justified at each step from left to right, I should present the original chain of equalities backwards. Then I can forget about the bound.

comment Convergence of a power series in the complex plane — does this argument work?
Thanks all. I think I'll type up the bounding of $|cos(nz)|$ once I've worked it out.

comment Determining where a function is complex differentiable
Thanks. I don't know how I missed that the equations are always satisfied when y=0. It's quite obvious now.

comment Why probability measures in ergodic theory?
The second question is addressed in this thread: mathoverflow.net/questions/31603/…

comment Composition series of the ring R of 3x3 real matrices as an R-module and as a Real-Module
Yes. Where I went wrong was considering subrings at all, right? Because ideals in $R$ are $R$-modules and it makes sense to consider their factors. This is all we need.

Thank you all. I'll look into these suggestions.

comment If G is a group of order n=35, then it is cyclic
I can't see what's wrong with it, but I have a hard time believing that so many people would overlook this proof it it were correct.
