DESCRIPTION:Analytic solutions for most PDEs are known only for some simpl
 e\ndomains\, such as a circle\, square\, or sphere. In order to obtain sol
 utions\nfor more realistic domains\, numerical approximations such as the\
 nfinite element method (FEM) and finite volume methods (FVM) are used.\nMe
 sh generation is a key step prior to these numerical\nmethods.  It is itse
 lf an active research topic with\nbackground in mathematics\, computer sci
 ence\, and engineering. Apart\nfrom numerical solution of PDEs\, its appli
 cations are numerous and have \npractical uses in fields such as archaeolo
 gy\, cinematography and robotics.\n\nIn this talk\, we will begin with tri
 angle mesh generation and adaptation in \nthe plane. This problem has been
  well studied. Efficient algorithms are \ndeveloped.  We will then move to
  tetrahedral mesh generation in 3d\, which is \nstill challenged by many t
 heoretical and practical issues. In this talk\, we \nwill highlight some r
 ecent development in this field.\n
