{wiki=K3_surface}
A K3 surface is a special type of complex smooth algebraic surface, characterized by several important properties. Here are the key features: 1. **Dimension and Arithmetic**: A K3 surface is a two-dimensional complex manifold (or algebraic surface) with a trivial canonical bundle, meaning that it has a vanishing first Chern class (\\(c_1 = 0\\)). This implies that its canonical divisor is numerically trivial.
