In this paper, we derive two new summation formulae for a class of series involving I � functions of several variables. These functions, which generalize many known special functions, play a crucial role in various branches of Mathematical analysis and applied Mathematics. By employing suitable techniques of summation and transformation, we establish compact and elegant expressions for these series under certain convergence conditions. These results contribute to the ongoing development of summation theorems for generalized special functions and may further applications in Mathematical analysis
