Banach Center Publications 92 (2011), 413-418 MSC: 46B04, 46B20, 46B25, 46B40, 46E30, 46A40, 46A80. DOI: 10.4064/bc92-0-29

#### Abstract

We will present relationships between the modular $\rho ^{\ast }$ and the norm in the dual spaces $(L_{\Phi })^{\ast }$ in the case when a Musielak-Orlicz space $L_{\Phi }$ is equipped with the Orlicz norm. Moreover, criteria for extreme points of the unit sphere of the dual space $(L_{\Phi }^{o})^{\ast }$ will be presented.
