Abstract: Eigenspace is a mathematical concept that is used to describe the set of all possible eigenvalues and eigenvectors of a linear operator. Within the context of deep water stratification under gravity modification and Coriolis effect, eigenspace plays an important role in understanding the dynamics of the deep water regime. Eigenspace is the vector space spanned by all eigenvectors corresponding to a given eigenvalue of a linear operator. In stratified deep water, the density variations modify the effective gravitational force experienced by fluid parcels, producing a slightly reduced buoyancy effect compared to the standard gravitational acceleration. These factors can cause the water to move in complex ways, and eigenspace can be used to describe the different modes of motion that are possible. The eigenspace of the linearized equations of motion for stratified deep water was used to identify wave modes such as internal gravity waves and inertial (Coriolis) waves. Importantly, we studied the regime of deep water stability under gravity modification and Coriolis effect. By examining the eigenvalues of the linearized equations of motion, we determined whether the deep water is stable or unstable, and if it is unstable, we identify the modes of motion responsible for the instability. The model is based on the Navier-Stokes equations, which describe the motion of fluid in a velocity field. The equations are modified to account for the effects of modified gravity and the Coriolis effect, which can cause the fluid to move in a curved path. The model is then solved using a combination of analytical and numerical techniques. The results show that the stability of stratified deep water under gravity modification and Coriolis effect is determined by a number of factors, including the magnitude of the modified gravity, the magnitude of the Coriolis effect, and the depth of the water. The model also shows that the stability of deep water regime under modified gravity and Coriolis effect conditions can be significantly different from that of deep water under normal gravity. The model has a number of potential applications, including the study of ocean currents and the design of underwater vehicles. It can also be used to study the stability of other fluids, such as gases and plasmas, under similar conditions
