Bott-Chern Harmonic Forms on Stein Manifolds (1806.00987v1)

Abstract: Let $M$ be an $n$-dimensional $d$-bounded Stein manifold $M$, i.e., a complex $n$-dimensional manifold $M$ admitting a smooth strictly plurisubharmonic exhaustion $\rho$ and endowed with the K\"ahler metric whose fundamental form is $\omega=i\partial\overline{\partial}\rho$, such that $i\overline{\partial}\rho$ has bounded $L^\infty$ norm. We prove a vanishing result for $W^{1,2}$ harmonic forms with respect to the Bott-Chern Laplacian on $M$.
