• Dirichlet Series 

      [SNAP-2014-001-EN] McCarthy, John E. (Mathematisches Forschungsinstitut Oberwolfach, 2014)
      Mathematicians are very interested in prime numbers. In this snapshot, we will discuss some problems concerning the distribution of primes and introduce some special infinite series in order to study them.
    • The Kadison-Singer problem 

      [SNAP-2014-008-EN] Valette, Alain (Mathematisches Forschungsinstitut Oberwolfach, 2014)
      In quantum mechanics, unlike in classical mechanics, one cannot make precise predictions about how a system will behave. Instead, one is concerned with mere probabilities. Consequently, it is a very important task to ...
    • Operator theory and the singular value decomposition 

      [SNAP-2014-009-EN] Knese, Greg (Mathematisches Forschungsinstitut Oberwolfach, 2014)
      This is a snapshot about operator theory and one of its fundamental tools: the singular value decomposition (SVD). The SVD breaks up linear transformations into simpler mappings, thus unveiling their geometric properties. ...
