In my previous work with Mishiba, we relate any positive characteristic multiple zeta value (MZV) to certain coordinate of the logarithm of an explicitly constructed t-module at a rational point. In this talk, we will define t-moitivic MZVs and t-motivic Carlitz multiple star polylogarithms, and show that their first several Taylor coefficients fill all coordinates of the logarithmic vector mentioned above. This is joint work with Green and Mishiba.
