Let BX denote the closed unit ball of X and B(x, r) denote the

closed ball with center at x [member of] X and radius r > 0.

x] = {x' [member of] PV | B(x, x') [less than or equal to] 0} is a

closed ball (spherical cap) on [?

Then, for each closed ball X [subset] E, there exists some (strongly) continuous affine operator [PHI] : E [right arrow] E such that, for every x [member of] X, one has

Let (E, <*, *>) be a Hilbert space, let K [subset] E be a closed ball and let [PHI] : E [right arrow] E be an affine (not necessarily continuous) operator such that

Let us assume that for every

closed ball B [subset] X there exists N with B [subset or equal to] [X.

Let [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] define as above, and B be any

closed ball in [R.

It seems to me now that the `centre,' rather than being a

closed ball encircling white, heterosexual, middle-class feminists, is really composed of only the people who refuse to hear and acknowledge anything but voices similar to theirs.

As for the rest of topologies, combination of the following items imply any

closed ball [B(H).

Indeed, if Z had a nonempty interior, then it would exist a

closed ball B, such that B [subset] Z, which implies

n], A is the

closed ball centered at the origin of [R.

1) Let b(H) be the set of all

closed balls in B(H).

Relatively weakly open sets in

closed balls of Banach spaces, and the centralizer.
