Almgren minimals sets, minimal cones, unions and products
Xiangyu Liang (Beihang University)

The notion of Almgren minimal sets is a way to try to solve Plateau’s problem in the setting of sets. To study local structures for these sets, one does blow-up at each point, and the blow-up limits turn out to be minimal cones. People then would like to know the list of all minimal cones.

The list of 1 or 2-dimensional minimal cones in are known for over a century. For other dimensions and codimensions, much less is known. Up to now there is no general way to classify all possible minimal cones. One typical way is to test unions and products of known minimal cones.

In this talk, we will first introduce basic notions and facts on Almgren minimal sets and minimal cones. Then we will discuss the minimality of unions and products of two minimal cones.
