Abstract: This study investigates a (2+1)-dimensional three-component nonlinear Schrödinger system featuring partially nonlocal nonlinearity under combined parabolic and linear potentials. To obtain optical soliton solutions, a variable mapping relation between nonautonomous and autonomous equations is established. Leveraging this mapping relation and applying the bilinearization method, vector soliton solutions are analytically derived, including both two-bright-one-dark one-soliton and two-soliton configurations. Furthermore, their space–time dynamics is examined and the formation of multi-layer and multi-hump structures influenced by the Hermite parameter is analyzed.
