Abstract:Abstract. We study a disc formula for the relative extremal function for a subset of a complex manifold and apply it to give a description of pluripolar sets and polynomial hulls.
“…The characterizations of Sadullaev [10], Levenberg-Poletsky [7], also cf. [3], of pluripolar hulls and their proof also hold for b-pluripolar sets. We will include this result with its very similar proof for convenience of the reader in Proposition 3.5.…”

“…It follows that the series v = ∞ j=1 v j is also uniformly convergent on compact sets in D \ {z}, hence it represents a plurisubharmonic function that is continuous up to ∂D \ {z} with boundary values ∞ j=1 F j on ∂D \ {z}. Then by (4) and (5) we have Zeriahi, [16] gave conditions under which a pluripolar set is completely pluripolar. Here we adapt Zeriahi's result to boundary pluripolar sets.…”

“…For z ∈ D one defines, cf. [10,8,3] (note that [3] appeared as [4], but in this latter paper there is little reference left to the boundary extremal function), ω(z, A, D) = sup{u(z) : u ∈ PSH(D), u ≤ 0, u * ≤ −1 on A}.…”
We present some basic properties of the so called boundary relative extremal function and shed some light on Sadullaev's question about behavior of different kinds of extremal functions. We introduce and discuss boundary pluripolar sets and boundary pluripolar hulls. For B-regular domains the boundary pluripolar hull is always trivial on the boundary of the domain. We present a "boundary version" of Zeriahi's theorem on the completeness of pluripolar sets.2010 Mathematics Subject Classification. 32U05.

Abstract. The paper gives an account of the work of Vyacheslav Pavlovich Zakharyuta in the domain of complex analysis, in particular pluripotential theory, showing the influence of his research during several decades.
We study the relation between certain alternative definitions of the boundary relative extremal function. For various domains we give an affirmative answer to the question of Sadullaev, [10], whether these extremal functions are equal.2010 Mathematics Subject Classification. 32U05.
