TIFR Mathematics 2024 | Part B | Question: 9
Suppose $f: X \rightarrow Y$ is a function between metric spaces, such that whenever a sequence $\left\{x_{n}\right\}$ converges to $x$ in $X$, the sequence $\left\{f\left(x_{n}\right)\right\}$ converges in $Y$ (but it is not given that the limit of $\left\{f\left(x_{n}\right)\right\}$ is $\left.f(x)\right)$. Then $f$ is continuous.

Let $R$ be the ring $\mathbb{C}[x] /\left(x^{2}\right)$ obtained as the quotient of the polynomial ring $\mathbb{C}[x]$ by its ideal generated by $x^{2}$. Let $R^{\times}$be the multiplicative group of units of this ring. Then there is an injective group homomorphism from $(\mathbb{Z} / 2 \mathbb{Z}) \times(\mathbb{Z} / 2 \mathbb{Z})$ into $R^{\times}$.
