%0 Journal Article %A Muñoz, Vicente %A Marco Perez, Ricardo %T On The genus of meromorphic of functions. %D 2015 %@ 1088-6826 %U https://hdl.handle.net/20.500.14352/34633 %X We define the class of Left Located Divisor (LLD) meromorphic functions, their vertical order m(0)(f) and their convergence exponent d(f). When m0(f) <= d(f) we prove that their Weierstrass genus is minimal. This explains the phenomena that many classical functions have minimal Weierstrass genus, for example, Dirichlet series, the Gamma-function, and trigonometric functions. %~
