In this paper we give complete characterizations, in terms of Dini numbers and integrals, of positive functions $\Phi(u)$ defined in $(0, \infty)$ satisfying the conditions: (i) $\Phi(u)/u^a$ is ...

This paper adopts a two-step technique to estimate structural vector error correction models and provides the asymptotic distribution of the impulse response ...

The study of partition functions is a significant area in number theory, focusing on how integers can be expressed as sums of other integers. Recent research has explored various inequalities related ...
