Giovanni Alberti coauthored a compactness theorem for <special functions of bounded variation> with <Carlo Mantegazza>. The result controls sequences that may contain jump discontinuities, using bounds on variation, gradients and jump sets. Such compactness is essential in <calculus of variations> problems where minimizing configurations can develop cracks or interfaces.<A Note on the Theory of SBV Functions by Giovanni Alberti and Carlo Mantegazza>[Introduction and Theorem 1.4]{ref}
