    • Variational Estimators in Statistical Multiscale Analysis 

      Li, Housen (2016-05-24)
      In recent years, a novel type of multiscale variational statistical approaches, based on so-called multiscale statistics, have received increasing popularity in various applications, such as signal recovery, imaging and ...

    • Analytic singularities near radial points 

      Zheng, Jiguang (2015-03-11)
      In this thesis, we applied tools of algebraic analysis and knowledge of symplectic geometry and contact geometry to give a normal form of certain class of microdifferential operators, and then studied analytic singularities of ...

    • Microlocal Analysis of Tempered Distributions 

      Schulz, René M. (2014-09-17)
      In this dissertation we study tempered distributions from the microlocal point of view. The fundamental notion of microlocal analysis, the wave front set, is replaced by two analogues, the SG-wave front set and the G-wave ...

    • C*-quantum groups with projection 

      Roy, Sutanu (2014-06-25)
      We propose a general theory to study semidirect products of C -quantum groups in the framework of multiplicative unitaries. Starting from a quantum group with a projection we decompose its multiplicative unitary as a product ...

    • Existence of solutions of quasilinear elliptic equations on manifolds with conic points 

      Nguyen, Thi Thu Huong (2014-05-15)
      Existence and regularity of solutions of quasilinear elliptic equations in nonsmooth domains have been interesting topics in the development of partial differential equations. The existence of finite-energy solutions of ...

    • Singularities of two-point functions in Quantum Field Theory 

      Wrochna, Michal (2013-08-28)
      The main topic of the present thesis is the study of singularities of two-point functions of spin-0 and spin-1/2 quantum fields, possibly set on curved spacetime or in the presence of smooth, external electromagnetic ...

    • Composition theorems for paired Lagrangian distributions 

      Nguyen, Nhu Thang (2012-04-12)
      The aim of this research is to determine whether the composition of paired Lagrangian distributions belongs to well-known classes such as marked Lagrangian, isotropic Lagrangian, paired Lagrangian or generalized ...
