We will describe derived categories of some (singular) projective curves and surfaces. A particularly nice case are surfaces with cyclic quotient singularities with connections to the Markov Diophantine equation. We do not assume familiarity with derived categories. If time permits, we will discuss higher dimensional examples (where Lucas's Theorem describing binomial coefficients mod p helps to show that certain components of the derived category are "indecomposable") building on ongoing joint work with Yujiro Kawamata & Nebojsa Pavic.
