Direct computation of period polynomials and classification of K3-fibred Calabi--Yau threefolds
Yuichi Enoki, Yotaro Sato, Taizan Watari
One can assign to four-dimensional N=2 supersymmetric Heterotic string vacua a set of classification invariants including a lattice and vector-valued modular forms. Some of t…

On odd number of fermion zero modes on solitons in quantum field theory and string/M theory
Yotaro Sato, Yuji Tachikawa, Taizan Watari
We argue that having an odd number of Majorana fermion zero modes on a dynamical point-like soliton signifies an inconsistency in a theory with 3+1 and higher dimensions. We check…
