Abstract:

In the present paper, we investigate the order of meromorphic solutions of the homogeneous linear differential-difference equations of the form:

An(z)f(n)(z+cn)+...+A1(z)f'(z+c1)+A0(z)f(z+c0)=0,

where c0, ..., cn are distinct complex numbers and A0(z), ..., An(z) are entire functions having the same order. Under some conditions on the coefficients, we improve and extend some results of Lan and Chen.

Keywords: Order of meromorphic function, difference equation, differential equation.
