Sobolev spaces have several important properties that make them useful for studying PDEs and optimization problems. For example, Sobolev spaces are Banach spaces, and they are also Hilbert spaces when \(p=2\) . Moreover, Sobolev spaces have the following embedding properties: ∣∣ u ∣ ∣ B V ( Ω

Variational analysis in Sobolev and BV spaces has several applications in PDEs and optimization. For example, consider the following PDE: For example, consider the following PDE: with boundary

with boundary conditions \(u=0\) on \(\partial \Omega\) . This PDE can be rewritten as an optimization problem: Sobolev spaces are Banach spaces

BV spaces are another class of function spaces that are widely used in image processing, computer vision, and optimization problems. The BV space \(BV(\Omega)\) is defined as the space of all functions \(u \in L^1(\Omega)\) such that the total variation of \(u\) is finite:
