KW - transcendental meromorphic function, small function, value distribution.
AB - <p style="text-align: justify;">In this paper we derive the fundamental inequality of the theorem of meromorphic functions. It extends some results of Yi Hong-xun et al. As one of its applications, we then study the value distribution of $f^{(k)} f^n - c(z)$.</p>
