## Abstract In Banach spaces ordered by a normal cone that contains interior points the positive invertibility of operators is studied. If there exists a uniformly positive functional then any positively invertible operator __A__ possesses a __B__ ‐decomposition, i.e., a positive decomposition __A_

## Abstract The paper is devoted to the investigation of the Helmholtz operators describing the propagation of acoustic waves in non‐homogeneous space. We consider the operator __A__ with a wave number __k__ such that where __k__~0~ is a positive function, __k__~±~ are complex constants with ℑ︁
