Pay attention to the names of the deleters of my answers.

Attack and deletion on 31/1/2015: (1).

There was a campaign, on October 25, 26, 2014 during the suspension of my account, for deleting some of my correct and accepted answers. Here is some of them: (1), (2), (3), (4), (5), (6), (7).

See what's going on with my answers (I), (II), (III). (4). They take the hints and ideas from my answers and then they down vote and delete them.

I posted this answer which is the solution to the problem and one of the most important results in complex variable yet it was simply converted to a comment!! This answer was down voted and deleted! I think it is my right to defend my answers.

Some deleted answers! Some of them are accepted and the other are correct. I just would like to keep them at hand.

(1)- (2)- (3)- (4)- (5).

$$ \sum_{k=1}^{n} j^{s}\ln(j)^{m}= \lim_{\alpha \to s } \zeta^{(m)}_{\alpha}( - \alpha ) + \zeta^{(m)}_{\alpha} \left( -\alpha,n+1 \right). $$

Do you know the definition for Riesz Basis?

There are existed methods for finding these asymptotic solutions.

Have you tried it for the case $n=3$?

Use the identity $\cos t=(e^{it} + e^{-it}) /2$.

comment nth derivative of ${1\over x}$. A problem.
For $(n-1)!$ $n$ starts from $1$. You should write the other formula down to see what I mean.

I think you mean the intersection line of the plane.

comment nth derivative of ${1\over x}$. A problem.
For the first one $n$ should start at $0$ and the second one $n$ should start at $1$.
