an entire function of bounded $L$-index in the direction}, volume={69}, url={http://umj.imath.kiev.ua/index.php/umj/article/view/1706}, abstractNote={We establish new criteria of boundedness of the $L$-index in the direction for entire functions in $C^n$. These criteria are formulated as estimate of the maximum modulus via the minimum modulus on a circle and describe the distribution of their
zeros and the behavior of the directional logarithmic derivative. In this way, we prove Hypotheses 1 and 2 from the article
[Bandura A. I., Skaskiv O. B. Open problems for entire functions of bounded index in direction // Mat. Stud. – 2015. – 43,
№ 1. – P. 103 – 109]. The obtained results are also new for the entire functions of bounded index in $C$. They improve the
known results by M. N. Sheremeta, A. D. Kuzyk, and G. H. Fricke.}, number={3}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={BanduraA. І. and SkaskivO. B.}, year={2017}, month={Mar.}, pages={426-432} }
