Abstract: In this note we revisit Almgren's theory of Qvalued functions, that are functions taking values in the space of unordered Qtuples of points in R^n. In particular: 1) we give shorter versions of Almgren's proofs of the existence of Dirminimizing Qvalued 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 Qvalued functions: f ∈W1,2(Ω,A Q)issaidtobeDirminimizingif Dir(f,Ω)≤Dir(g,Ω) forallg∈W1,2(Ω,A Q)withf ∂Ω =g ∂Ω. The main results proved in this paper. We are Qvalued functions revisited book ready to state the main theorems of Almgren reproved in this note: an existence theorem and two regularityresults.

Almgren’s QValued Functions Revisited CamilloDeLellis∗ Abstract In a pioneering work written 30 years ago, Almgren developed a farreaching regularity theory for areaminimizing currents in codimension higher than 1.
Building upon Almgren’s work, Chang proved later the optimal regularity statement for 2dimensional 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 Dirminimizing multiple valued functions and the approximation of areaminimizing currents with small cylindrical excess.
