摘要:In this paper, we investigate zeros and α-points of meromorphicsolutions f ( z ) for difference Riccati equations, and we obtain someestimates of exponents of convergence of zeros and α-points of f ( z ) and shifts f ( z + n ) , differences Δ f ( z ) = f ( z + 1 ) − f ( z ) , and divided differences Δ f ( z ) f ( z ) .
