Title: The C-motivic wedge subalgebra

Abstract: The motivic Adams spectral sequence is used to compute the homotopy groups of the sphere spectrum. To run the motivic Adams spectral sequence, one begins with the cohomology Ext_A(M_2, M_2) of the motivic Steenrod algebra. Unfortunately, the cohomology Ext_A(M_2, M_2) is infinitely generated and seems irregular. We have found out the regular behavior in the motivic wedge which is a subalgebra of Ext_A(M_2, M_2). In my talk, I will introduce the motivic wedge subalgebra and a conjecture on the behavior of the family e_0^t g^k in Ext_A(M_2, M_2).
