*Title:* Mixed Hodge structures: an invitation

*Abstract:* The cohomology of an algebraic variety carries extra 
symmetries beyond what the underlying topological space sees. For smooth 
projective varieties, these symmetries are captured by the so-called 
Hodge decomposition. When you drop the assumptions of smoothness or 
projectivity, these symmetries break down in a controlled way, recorded 
by a notion of weight. In this talk, we will explore these symmetries in 
the concrete case of curves: elliptic curves where everything works 
perfectly, and singular or non-compact curves where the structure 
changes in measurable ways.
