• Construction of vector-valued modular integrals and vector-valued mock modular forms 

  Gimenez J.; Muhlenbruch T.; Raji W. (Kluwer Academic Publishers;, 2014)

  It is known that, given a vector-valued modular form of negative weight, its Fourier coefficients can be calculated based on the principal part of the form. In this paper we start with an arbitrary principal part and ...

• The tree model of a meromorphic plane curve 

  Assi A. (Real Acadademia de Ciencias; MILANVIA DECEMBRIO, 28, MILAN, 20137, ITALY, 2014)

  We associate with a plane meromorphic curve f a tree model T(f) based on its contact structure. Then we give a description of the y-derivative of f (resp. the Jacobian J(f, g)) in terms of T(f) (resp. T(f, g)). We also ...
