Approximate Birkhoff-James orthogonality preserver on Lebesgue-Bochner spaces

In this article, we examine an approximate version of Koldobsky-Blanco-Turnšek theorem (namely, Property P) in the space of vector-valued integrable functions. More precisely, we prove that the Lebesgue-Bochner spaces $L^p(μ,X),\;(1\leq p<\infty)$, do not have Property P under certain conditions on $μ$ and the Banach space $X$.
