Abstract: The present thesis is divied in two parts. In the first part of the thesis we develop a theoretical method able to describe double excitations in absorption experiments. In particular a coherent approach to the description of double excitations in correlated materials is presented: we derive stringent mathematical conditions on the algebraical structure of the Bethe-Salpeter and TDDFT kernels that avoid the occurrence of spurious and non-physical excitations. We discuss how these conditions need
