  We show explicit the first radiative correction for the vertex and
photon-photon 4-point function in Generalized Scalar Duffin-Kemmer-Petiau
Quantum Electrodynamcis (GSDKP), utilizing the dimensional regularization
method, where the gauge symmetry is manifest. As we shall see one of the
consequences of the study is that the DKP algebra ensures the functioning of
theWard- Takahashi-Fradkin (WTF) identities in the first radiative corrections
prohibiting certain ultraviolet (UV) divergences. This result leads us to ask
whether this connection between DKP algebra, UV divergences, and quantum gauge
symmetry (WTF) is a general statment.
