Summary: | Let
be a probability space and
the algebra of equivalence classes of realvalued random variables on
. When
is endowed with the topology of convergence in probability, we prove an intermediate value theorem for a continuous local function from
to
. As applications of this theorem, we first give several useful expressions for modulus of random convexity, then we prove that a complete random normed module (
S
, ‖·‖) is random uniformly convex iff
L
p
(
S
) is uniformly convex for each fixed positive number
p
such that 1 <
p
< +∞. |
