Let f be

bounded function of soft sets attaining the bound parameterwise in an interior point of [mathematical expression not reproducible] and differentiable on [mathematical expression not reproducible].

We point out that in [6] the authors considered M(x, u) as a

bounded function and

for some positive number [[lambda].sub.0], where p(t) is a nonnegative

bounded function. Suppose further that

Moreover, assume that there exists a

bounded function [[gamma].sub.2] : [0, [infinity]) [right arrow] [0, [infinity]) with li[m.sub.t[right arrow]0]+ [[gamma].sub.2](t) = 0 such that

where r is a

bounded function, ([[epsilon].sub.t]) is a square integrable process, and et and ([X.sub.t]) are independent.

Suppose that, for each n [greater than or equal to] 0, [u.sub.n] (r) is a

bounded function for a [less than or equal to] r [less than or equal to] b.

In the recent paper [10], Theorem 3.2 (iv), applying this idea to the classical Whittaker's cardinal series, we have obtained a Jackson-type estimate in terms of [[omega].sub.1][(f; 1/W).sub.R], in approximation of a continuous, positive and

bounded function a [member of] [L.sup.2] (0, [infinity]) satisfying the inequality [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII].

Let q > 1 and f : [0,1] [right arrow] C be a

bounded function, such that f [member of] C[0, a], 0 < a [less than or equal to] 1.

If f : {1,2, ..., N} x R [right arrow] R is a continuous and

bounded function, then BVP (2.2) has a solution.
