## Abstract

We introduce and study a multiparameter Poisson process (MPP). In a particular case, it is observed that the MPP has a unique representation. Its subordination with the multivariate subordinator and inverse subordinator are studied in detail. Also, we consider a multivariate multiparameter Poisson process and establish its connection with the MPP. An integral of the MPP is defined, and its asymptotic distribution is obtained. Later, we study some properties of the multiparameter martingales. Moreover, the multiparameter martingale characterizations for the MPP and its subordinated variants are derived.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
