DESCRIPTION:Title: <a href="https://researchseminars.org/talk/DQSeminar/4/
 ">Asymptotic equivalence of two strict deformation quantizations and appli
 cations to the classical limit</a>\nby Christiaan van de Ven (University o
 f Trento) as part of Deformation Quantization Seminar\n\n\nAbstract\nThe c
 oncept of strict deformation\n  quantization provides a mathematical forma
 lism that describes the\n  transition from a classical theory to a quantum
  theory in terms of\n  deformations of (commutative) Poisson algebras (rep
 resenting the\n  classical theory) into non-commutative $C^*$-algebras\n  
 (characterizing the quantum theory). In this seminar we introduce\n  the d
 efinitions\, give several examples and show how quantization of\n  the clo
 sed unit 3-ball $B^3 \\subset \\mathbb{R}^3$ is related to\n  quantization
  of its smooth boundary (i.e. the two-sphere\n  $S^2 \\subset \\mathbb{R}^
 3$.) We will moreover give an application\n  regarding the classical limit
  of a quantum (spin) system and discuss\n  the concept of spontaneous symm
 etry breaking (SSB).\n
