The authors derive several integral inequalities associated with two intere
sting subclasses S(p, n, alpha) and K(p, n, alpha) of the class A(p, n) of
p-valent analytic functions with missing coefficients. They also investigat
e various properties and characteristics of two further classes T-lambda*(p
, alpha) and C-lambda(p, alpha) of p-valent analytic functions in A(p, 1),
which are introduced in this paper. Relevant connections of the various res
ults presented here with those in earlier works are indicated. (C) 2000 Els
