$\nabla$-Fredgolm operators in Banach-Kantorovich spaces


The paper is devoted to studying $\nabla$-Fredholm operators in Banach-Kantorovich spaces over a ring of measurable functions. We show that a bounded linear operator acting in Banach-Kantorovich space is $\nabla$-Fredholm if and only if it can be represented as a sum of an invertible operator and a cyclically compact operator.
