Abstract:
We prove the existence of a global attractor of a regularized Euler–Bardina system with dissipation on the two-dimensional sphere and in arbitrary domains on the sphere. Explicit estimates for the fractal dimension of the attractor in terms of its physical parameters are obtained.
Keywords:
Euler's system, Bardina's model, attractors, fractal dimension, spectral inequalities on the sphere.
