| (Almost) 25 Years of DMRG - What Is It About? |
In this talk, I will introduce DMRG both from the historical (statistical) and modern (matrix product state) perspective, highlighting why it has become the method of choice for one-dimensional quantum systems in and out of equilibrium. |

| Openness of a Many-fermion Quantum System from the Generalized Pauli Principle |
Information about the interaction of a many-electron quantum system with its environment is encoded within the one-electron density matrix (1-RDM). |

| Generalized Pauli Constraints in Reduced Density Matrix Functional Theory |
Reduced Density Matrix Functional Theory is a method that relies on the 1-1 correspondence between the ground state wavefunction of many electron systems and the first order reduced density matrix(1RDM) and uses the second one as its fundamental valuable. |

| Quasipinning and Extended Hartree-Fock Method based on Generalized Pauli Constraints |
It is now known that fermionic natural occupation numbers (NON) do not only obey Pauli’s exclusion principle but are even stronger restricted by the so-called generalized Pauli constraints (GPC). |

| Fermionic Exchange Symmetry: Quantifying its Influence beyond Pauli’s Exclusion Principle |
The Pauli exclusion principle has a strong impact on the properties and the behavior of most fermionic quantum systems. Remarkably, even stronger restrictions on fermionic natural occupation numbers follow from the fermionic exchange symmetry. |

| Quantum Marginal Problem and Generalized Pauli Constraints |
I will give an introduction to the univariate quantum marginal problem using an elementary mathematical point of view. In particular, I will explain how extremality of the local spectrum carries structural information about the global wave function. |

| Two-electron Reduced Density Matrices in Quantum Chemistry and Physics |
Strongly correlated quantum systems are not easily described with conventional quantum chemistry formalism because the number of non-negligible configurations grows exponen- tially with the number of orbitals actively participating in the correlation. |
