问题 1.

(3 in Rudin) Prove Proposition 1.15: The axioms of multiplication imply the following statements for all $x, y$, and $z$ in a field $F$.
(a) If $x \neq 0$ and $x y=x z$ then $y=z$.
(b) If $x \neq 0$ and $x y=x$ then $y=1$.
(c) If $x \neq 0$ and $x y=1$ then $y=1 / x$.
(d) If $x \neq 0$ then $1 /(1 / x)=x$.
Note that (b) and (c) assert the uniqueness of the multiplicative identity and the multiplicative inverse respectively.

问题 2.

(5 in Rudin) Let $A$ be a nonempty set of real numbers which is bounded below. Let $-A$ be the set of all numbers $-x$, where $x \in A$. Prove that
$$
\inf A=-\sup (-A)
$$
Where the $\inf A$ is defined to be the greatest lower bound of $A$.

问题 3.

(8 in Rudin) Prove that no order can be defined in the complex field that turns it into an ordered field. Hint: -1 is a square.

问题 4.

(10 in Rudin) Suppose $z=a+i b, w=u+i v$, and
$$
a=\left(\frac{|w|+u}{2}\right)^{1 / 2}, \quad b=\left(\frac{|w|-u}{2}\right)^{1 / 2}
$$
Prove that $z^2=w$ if $v \geq 0$ and that $(\bar{z})^2=w$ if $v \leq 0$. Conclude that every complex number (with one exception!) has two complex square roots.

问题 5.

(13 in Rudin, this is often called the Reverse Traingle Inequality) If $x, y$ are complex, prove that
$$
|| x|-| y|| \leq|x-y|
$$
