Measures of growth and approximation of entire harmonic functions in n-dimensional space in some Banach spaces

The relationship between the classical order and type of an entire harmonic function in space Rn, n≥3, and the rate of its best harmonic polynomial approximation for some Banach spaces of functions harmonic in the ball of radius R has been studied.
