Abstract

In this paper we establish a relation between classes of ω-plurisubharmonic functions Ep(X,ω),p>0 and DMAloc(X,ω) introduced and investigated by Guedj and Zeriahi (J. Funct. Anal., 250:442–482, 2007) and Cegrell (Acta Math., 180:187–217, 1998; Ann. Inst. Fourier (Grenoble), 54:159–179, 2004), respectively, on a compact Kähler manifold $$. We show that En1(X,ω)DMAloc(X,ω) but 0<p<n1Ep(CPn,ω)DMAloc(CPn,ω). At the same time we investigate a relation between the classes DMA(Cn)L(Cn) and DMA(CPn,ω) as well as DMA^(Cn)L(Cn) and DMA^(CPn,ω).
