The corresponding scalar and vector fields equation are found. Equations are presented, which are equivalent to those of a scalar field with conformal coupling and electromagnetic field with non-minimal coupling to the curvature. The gauge-invariant Duffin-Kemmer-Petiau equation with non-minimal coupling is given.LATEX, 4 pages, no figureGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
