%0 Journal Article %T Sectorial oscillation of linear differential equations and iterated order %A Zhao-Jun Wu %A Dao-chun Sun %J Electronic Journal of Differential Equations %D 2004 %I Texas State University %X In the present paper, we investigate higher order linear differential equations with entire coefficients of iterated order. Using value distribution theory of transcendental meromorphic functions and covering surface theory, we extend a result on the order of growth of solutions published by Bank and Langley [2]. %K Iterated order %K iterated convergence exponent %U http://ejde.math.txstate.edu/Volumes/2007/134/abstr.html
