For an invertible $n$-by-$n$ matrix $M$ show the transpose is also invertible. As the title says, if I have a $n$-by-$n$ matrix $M$ which is invertible how do I show that the transposed matrix is invertible with ${({M...
Since $M$ is invertible, $MM^{-1}=I$. Transposing both sides produces $(MM^{-1})^t=(M^{-1})^tM^t=I^t=I$, so $M^t$ is invertible with inverse $(M^{-1})^t$. That is, $(M^t)^{-1}=(M^{-1})^t$.

Is this fact about matrices and linear systems true? Let $A$ be a $m$-by-$n$ matrix and $B=A^TA$. If the columns of $A$ are linearly independent, then $Bx=0$ has a unique solution. If is true, can you help me prove i...
Yes. If $Bx=0$, then $x^T B x = (Ax)^T (Ax) = \|Ax\|^2 = 0$. Since the columns of $A$ are linearly independent, $Ax=0$ iff $x=0$. Hence $x=0$ and the solution to $Bx=0$ is not just unique, it is zero.

Definition of finite-by-nilpotent In group theory what are definitions of: 1. finite-by-nilpotent, 2. nilpotent-by-finite, 3. abelian-by-finite, 4. or in general: *-by- *?
A group $G$ is called X-by-Y if it has a normal subgroup $N$ that belongs to the class X and the quotient $G/N$ belongs to the class Y.

When are powers of square matrices linearly independent? If I have an $n$-by-$n$ matrix $A$, is $1, A, A^2,...,A^{n^2}$ always linearly independent?
No, never, because the space of $n\times n$ matrices has dimension $n^2$ and you have $n^2+1$ matrices there.

Can we conclude that this matrix is definite positive? Let $A$ be a $n\text{-by-}m$ matrix. Suppose that columns of $A$ are linearly independent. Can we conclude that $A^TA$ is definite positive? Could you help me wit...
Observe that for any $\xi \in \mathbb{R}^m$, $$ \langle \xi, A^T A \xi \rangle_{\mathbb{R}^m} = \langle A \xi, A \xi \rangle_{\mathbb{R}^n} = \|A \xi \|^2_{\mathbb{R}^n}. $$ Now: 1. What do you know about the sign of $\|A \xi \|^2_{\mathbb{R}^n}$? 2. Given that the columns of $A$ are linearly indepe...
