Abstract: In this note we revisit Almgren's theory of Q-valued functions, that are functions taking values in the space of unordered Q-tuples of points in R^n.

In particular: 1) we give shorter versions of Almgren's proofs of the existence of Dir-minimizing Q-valued functions, of their Hoelder regularity and of the dimension estimate of their singular set; 2) we propose an alternative. Hence, we can formulate a Dirichlet problem for Q-valued functions: f ∈W1,2(Ω,A Q)issaidtobeDir-minimizingif Dir(f,Ω)≤Dir(g,Ω) forallg∈W1,2(Ω,A Q)withf| ∂Ω =g| ∂Ω.

Almgren’s Q-Valued Functions Revisited CamilloDeLellis∗ Abstract In a pioneering work written 30 years ago, Almgren developed a far-reaching reg-ularity theory for area-minimizing currents in codimension higher than 1.

Build-ing upon Almgren’s work, Chang proved later the optimal regularity statement for 2-dimensional currents. In some recent papers the author, in collaboration with Emanuele Spadaro, has simplified and extended some results of Almgren's theory, most notably the ones concerning Dir-minimizing multiple valued functions Q-valued functions revisited book the approximation of area-minimizing currents with small cylindrical excess.

On the conceptual level this invites for an investigation of leadership as a conception, e.g. it should be considered whether the tasks earlier addressed as management functions can be properly described and explained by one or more specific kinds of leadership or whether.

both the numerator and denominator approach zero. Typically this difficulty can be resolved when $$f$$ is a "nice'' function and we are trying to compute a derivative. Occasionally such limits are interesting for other reasons, and the limit of a fraction in which both numerator and denominator approach zero can be difficult to analyze.
