Example 20.2.975F5F5ACD2FA

Example 20.2.9.75F5F5ACD2FAAs a trivial example, when $Y$ is just a single point, then $\mathrm{QPSH}(Y)$ is canonically identified with $\mathbb {R}$. Any constant $c\in \mathbb {R}$ is a trace operator of a function $\varphi \in \mathrm{QPSH}(X)$ satisfying $\nu (\varphi ,Y)=0$.
