Some harmonic problems on the tangent bundle with a berger-type deformed sasaki metricAltunbas, MuratSimsek, RamazanGezer, AydinBerger type deformed Sasaki metricHarmonic mapsRiemannian metricsTangent bundlePhysicsHarmonic problemsHarmonicityVector fieldsMathematical techniquesLet (M2k, ϕ, g) be an almost anti-paraHermitian manifold and (T M, gBS) be its tangent bundle with a Berger type deformed Sasaki metric gBS . In this paper, we deal with the harmonicity of the canonical projection π: T M → M and a vector field ξ which is considered as a map ξ: M → T M. © 2020, Politechnica University of Bucharest.
