“…A similar version of such an approximation theorem on admissible sets was recently obtained for conformal minimal immersions, null curves [10,11] and for holomorphic Legendrian curves [11,12].…”
Based on the Runge theorem for generalized analytic vectors proved by Goldschmidt in 1979, we provide a Mergelyan-type and a Carleman-type approximation theorems for solutions of Pascali systems.

“…In Section 9 we survey recent results concerning the problem of Paul Yang from 1977, asking whether there are bounded (metrically) complete complex submanifolds of C n . (This is holomorphic analogue of the Calabi-Yau problem concerning minimal surfaces in R n for n ≥ 3; see [8,Chapter 7] for the latter.) It has been discovered fairly recently that the ball of C n and, more generally, any pseudoconvex Runge domain in C n can be foliated by complete complex submanifolds of any codimension and with partial control of the topology of the leaves.…”
In this paper we expose the impact of the fundamental discovery, made by Erik Andersén and László Lempert in 1992, that the group generated by shears is dense in the group of holomorphic automorphisms of a complex Euclidean space of dimensions n > 1. In three decades since its publication, their groundbreaking work led to the discovery of several new phenomena and to major new results in complex analysis and geometry involving Stein manifolds and affine algebraic manifolds with many automorphisms. The aim of this survey is to present the focal points of these developments, with a view towards the future.

“…This led to an essentially optimal solution of the Calabi-Yau problem for minimal surfaces, originating in conjectures of Eugenio Calabi from 1965; see Theorems 3.5 and 3.6. This technique was also used in the construction of complete proper minimal surfaces in minimally convex domains of R (see [16,Chapter 8]).…”
This is an expanded version of my plenary lecture at the 8th European Congress of Mathematics in Portorož on 23 June 2021. The main part of the paper is a survey of recent applications of complex-analytic techniques to the theory of conformal minimal surfaces in Euclidean spaces. New results concern approximation, interpolation, and general position properties of minimal surfaces, existence of minimal surfaces with a given Gauss map, and the Calabi-Yau problem for minimal surfaces. To be accessible to a wide audience, the article includes a self-contained elementary introduction to the theory of minimal surfaces in Euclidean spaces.
