Abstract:

In the paper, the authors investigate the exponent of convergence of the zero-sequence of meromorphic solutions to homogeneous linear differential equation f(k)+Ak-2f(k-2)+…+A1f'+A0f=0  when its  coefficients are meromorphic functions possessing only a finite number of poles and dominant coefficient As(s∈{2, …, k-2})  is fabry gap. The  minimum number of linear independent transcendental solutions and the maximum number of linear independ ent transcendental solutions with finite exponents of convergence of the zero-sequence are obtained.

Key words: Differential equation, Fabry gap, Linearly independent, Exponent of convergence of zero-sequence
