Classifying $L$-functions of (very) low degree: I will introduce a set of Dirichlet series $\mathfrak{A}^{\#}$ which is known to contain the most interesting examples that arise from the theory of automorphic forms. This set is considerably larger than the extended Selberg class ${\mathcal S}$ defined by Kaczorowski and Perelli. Associated to each element in this set is an invariant real number $d$ called the degree. I will try and explain how to classify elements of ${\mathfrak A}^{\#}$ with $d<2$. Time permitting, I will give some applications to the study of zeros of automorphic $L$-functions. Some of these results have been obtained in collaboration with R. Balasubramanian.
