| Abstract. This work investigates the existence and uniqueness of mild solutions for a specific class of stochastic partial integrodifferential equations in Hilbert spaces by developing Picard-type approximate sequences. We provide approximate results based on Taniguchi conditions. Additionally, we apply these abstract findings to the Heath-Jarrow-Morton-Musiela (HJMM) equation to reinforce the theoretical framework. | |
