Book project
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:
- C.-Y. Hsu, Z. Jin and R. Sakamoto, Euler systems for GSp(4) x GL(2). (Arxiv)
Papers in press
- D. Loeffler and C. Williams, P-adic L-functions for GL(3). To appear in Math. Annalen. (Arxiv)
- D. Loeffler, R. Rockwood and S.L. Zerbes, Spherical varieties and p-adic families of cohomology classes. To appear in Elliptic curves and modular forms in arithmetic geometry – celebrating Massimo Bertolini's 60th birthday. (Arxiv)
