A theory of non-absolutely convergent integrals in Rn with singularities on a regular boundary

W. Jurkat, D. Nonnenmacher (1994)

Fundamenta Mathematicae

Specializing a recently developed axiomatic theory of non-absolutely convergent integrals in $ℝ^{n}$ , we are led to an integration process over quite general sets $A \subseteq q ℝ^{n}$ with a regular boundary. The integral enjoys all the usual properties and yields the divergence theorem for vector-valued functions with singularities in a most general form.

A two-weight inequality for the Bessel potential operator

Yves Rakotondratsimba (1997)

Commentationes Mathematicae Universitatis Carolinae

Necessary conditions and sufficient conditions are derived in order that Bessel potential operator $J_{s, λ}$ is bounded from the weighted Lebesgue spaces $L_{v}^{p} = L^{p} (ℝ^{n}, v (x) d x)$ into $L_{u}^{q}$ when $1 < p \leq q < \infty$ .

A unified approach to several inequalities involving functions and derivatives

Javier Duoandikoetxea (2001)

Czechoslovak Mathematical Journal

There are many inequalities measuring the deviation of the average of a function over an interval from a linear combination of values of the function and some of its derivatives. A general setting is given from which the desired inequalities are obtained using Hölder’s inequality. Moreover, sharpness of the constants is usually easy to prove by studying the equality cases of Hölder’s inequality. Comparison of averages, extension to weighted integrals and $n$ -dimensional results are also given.
