I have a B.Sc in computer science and a B.Sc in mathematics from the Technion.

I am interested mainly in abstract algebra and I hope to start graduate school soon to continue study some advanced topics in this area.

Currently I am going over Abstract Algebra by Dummit and Foote to recall old topics and fill some gaps I have, while working full time as a programmer.

comment $A$ matrix, $+i, -i$ are eigenvalues.
@user3628041 note that the determinant is zero iff one of the eigenvalues is zero and use Surb answer to complete the argument that indeed the implication I made holds

comment How on earth will anyone prove $n^3-3n^2+n-1=Θ(n^3)$
Yes you can, it follows from the definition

comment $T: M_{2\times 2}(R) \rightarrow M_{2 \times 2}(R)$ linear map
@IlanAizelmanWS use the standard basis (all entries are 0 except for one entry which is 1). Work with 4 dimensional coordinate vectors to represent an element of V
