To determine the stable homotopy groups of spheres is one of the central problems in homotopy theory. One of the main tools to approach it is the classical Adams spectral sequence. In this talk, we will introduce the method of compute product elements in the Adams spectral sequence and discuss some nontrivial products in the stable homotopy groups of spheres.
