The size of the singular set of area-minimizing currents
Pages: 1 – 83
A well-known monograph of Almgren proves that the singular set of a general $n$-dimensional area-minimizing integral currents has dimension at most $n-2$, which is an optimal bound when the dimension of the ambient manifold is larger than $n+1$. Almgren’s original (typewritten) manuscript was more than 1700 pages long. In a recent series of works with Emanuele Spadaro we have given a substantially shorter and simpler version of Almgren’s theory, building upon large portions of his program but also bringing some new ideas from partial differential equations, metric analysis and metric geometry.
