    • A converse theorem for Jacobi cusp forms of degree two 
      Kohnen, Winfried; Shankhadhar, Karam Deo; Martin, Yves (Institute of Mathematics. Polish Academy of Sciences, 2019)
    • On product expansions of generalized modular forms 
      Kohnen, Winfried; Martin, Yves (2008)
      We give examples of generalized modular forms with the property that their divisors are supported at the cusps and the exponents in their q-product expansions take infinitely many values. © 2007 Springer Science+Business ...
    • Products of two Eisenstein series and spaces of cusp forms of prime level 
      Kohnen, Winfried; Martín González, Yves Leopoldo (Ramanujan Mathematical Society, 2008)
      Using the Rankin-Selberg method and Eichler-Shimura cohomology we give a set of generators for the space of cusp forms of odd prime level and even weight ≥ 4 whose elements are the cuspidal parts of products of two specific ...
    • Sign changes of Fourier coefficients of cusp forms supported on prime power indices 
      Kohnen, Winfried; Martin, Yves (World Scientific Publishing Co. Pte Ltd, 2014)
      © World Scientific Publishing Company. Let f be an even integral weight, normalized, cuspidal Hecke eigenform over SL2(Z) with Fourier coefficients a(n). Let j be a positive integer. We prove that for almost all primes σ ...
