Abstract

Let X be a space and <TEX>$2^X$</TEX>(C(X);K(X);<TEX>$C_K$</TEX>(X)) denote the hyperspace of nonempty closed subsets(connected closed subsets, compact subsets, subcontinua) of X with the Vietoris topology. We investigate the relationships between the space X and its hyperspaces concerning the properties of connectedness im kleinen. We obtained the following : Let X be a locally compact Hausdorff space. Let <TEX>$x{\in}X$</TEX>. Then the following statements are equivalent: (1) X is connected im kleinen at <TEX>$x$</TEX>. (2) <TEX>$2^X$</TEX> is arcwise connected im kleinen at {<TEX>$x$</TEX>}. (3) K(X) is arcwise connected im kleinen at {<TEX>$x$</TEX>}. (4) <TEX>$C_K$</TEX>(X) is arcwise connected im kleinen at {<TEX>$x$</TEX>}. (5) C(X) is arcwise connected im kleinen at {<TEX>$x$</TEX>}.
