Together with Sarah Zerbes, I am assembling a book Euler systems and the Bloch–Kato conjecture: the case of GSp(4) ×GL(2) and GSp(4) × GL(2) × GL(2). This includes the following papers of which I am an author:

  • D. Loeffler and S.L. Zerbes, P-adic L-functions and diagonal cycles for GSp(4) x GL(2) x GL(2). (Arxiv)
  • D. Loeffler and S.L. Zerbes, On p-adic regulators for GSp(4) x GL(2) and GSp(4) x GL(2) x GL(2). (Arxiv)
  • D. Loeffler and S.L. Zerbes, On the Bloch–Kato conjecture for GSp(4) x GL(2). (Arxiv)
  • D. Loeffler, On some zeta-integrals for unramified representations of GSp(4). (Arxiv)

This collection will also include the following papers by other authors:
