Let $k$ be as in Theorem … (ii) is actually a Weihrauch equivalence. The details of the proof still need to be adjusted, so the claimed equivalence is left as an open problem.

Let $\text{\rm\sffamily CC}_2$ denote connected choice for non-empty connected closed subsets of $[0,1]^2$. For a multi-valued operation $f$, write $\operatorname{id}\times f$ for…

Let $\text{\rm\sffamily CC}_2$ denote connected choice for non-empty connected closed subsets of $[0,1]^2$. For a multi-valued operation $f$, write $f\times f$ for two parallel ins…

Let $\text{\rm\sffamily CC}_2$ be connected choice for non-empty connected closed subsets of $[0,1]^2$, and let $\text{\rm\sffamily C}_{[0,1]}$ be closed choice on the unit interva…

Let $\text{\rm\sffamily CC}_n$ denote connected choice for subsets of $[0,1]^n$, and let $\text{\rm\sffamily C}_{[0,1]}$ denote closed choice on the unit interval. Weihrauch reduci…
