In this paper, we consider the dynamics of Klein-Gordon and Dirac oscillators in (2+1) dimensions with noncommutativity of the spatial coordinates using the supersymmetric path integral formalism. The propagator is calculated and the energy eigenvalues with their corresponding eigenfunctions are deduced.

We study a systematic method to obtain the general vertex functions (of Neveu-Schwarz sector), which are used in the covariant path integral approach to the open bosonic and superstring theories. For the superstring the superspace formulation in the Wess-Zumino gauge is used to construct the vertices at the boundaries of world sheets. For both theories the vertex functions are explicitly obtained for the first four mass levels and coincide with those in the operator formalism.
