Abstract:
We show that many 2-dimensional Artin group are residually finite. This includes Artin groups on three generators with labels at least 3, where either at least one label is even, or at most one label is equal 3. The result relies on decomposition of these Artin groups as free product with amalgamation of finite rank free groups.
