Some examples of algebraic surfaces with canonical map of degree 20
In this note, we construct two minimal surfaces of general type with geometric genus $ p_g = 3 $, irregularity $ q = 0 $, self-intersection of the canonical divisor $ K^2 = 20, 24 $ such that their canonical map is of degree $ 20 $. In one of these surfaces, the canonical linear system has a non-tri...
