I have a B.A. in Mathematics from the University of Chicago. I am starting a Ph.D. in Linguistics on September 2014 in the same university.

comment Is this $\beta$-reduction well defined?
The question is whether it is possible to operate as it is.

comment A step in the proof of the Riemann Mapping Theorem
Are we considering the graph of $sin(1/x)$ as a subset of $\overline{\Bbb C}$?

comment Abelian group admitting a surjective homomorphism onto an infinite cyclic group
I just realised my stupid mistake! Just one more thing. How can I show that any element of $G$ is expressible as a product of two elements, the first of which is from $\ker(f)$ and the second from $im(g)$?

Thank you very much! It is all clear now!

comment Abelian group admitting a surjective homomorphism onto an infinite cyclic group
I have tried to show that $\ker(g)$ is trivial, but I am failing to do so. My problem is that the $x$ you chose above might have finite order so you would have $nx=0$ with $n \neq 0$ thus the kernel will not be trivial. I cannot find a method to by-pass this problem.

comment Abelian group admitting a surjective homomorphism onto an infinite cyclic group
I am so very sorry for not understanding this immediately. Here is my point of confusion. I cannot see how $G = \ker(f) \times im(g) \implies G \cong \ker(f) \times \Bbb Z$, since $im(g) \subset G$ so you would get $G \cong \ker(f) \times im(g) \subset \ker(f) \times G$

Dear Brian, I would like to ask your permission to integrate your suggestions and hints into a complete answer in my original post. May I do so?

Thank you! I will try to extend this as much as possible and provide links to other resources too. Did you check the one suggested in the update I made?

comment Definite Integral with a discontinuty
I don't think the problem is the discontinuity itself, but rather the fact that the integrand seems to blow up at $x = 0$.

comment Differential Equation : $f '' = f '$
You are indeed correct to point out that flaw. But that does not mean the proof is not rigorous. It only means that there is one more case to be checked. I will add it.

No harm done! (:

comment Differential Equation : $f '' = f '$
That's impossible! The first derivative will be some number but the second will be 0. How are they working?

Thank you for pointing that out! Thanks @Chris Taylor for editing the solution.

comment Mathematical preparation for postgraduate studies in Linguistics
Would that refer to thesis advisors for mathematics or for linguistics? And you refer to the Ph.D. dissertation or an undergraduate B.A. thesis? If you are referring to the latter, we do not need to complete one, it is not a requirement for graduation.
