Michael's selection theorem states that a lower hemicontinuous multivalued map with nonempty convex closed values $displaystyle Fcolon Xrightrightarrows E$ from a paracompact space $X$ to a Banach space $E$ admits a continuous selection.
If we replace the assumption "lower hemicontinuous multivalued map with nonempty convex closed values" by one of the following assumptions, does the theorem still hold?
- "hemicontinuous multivalued map with nonempty closed values".
- "lower hemicontinuous multivalued map with nonempty connected closed values".
