Motivic apsects of a remarkable class of Calabi-Yau threefolds
Gregory Pearlstein, Chris Peters
In this note we consider the motivic aspect of the middle cohomology of more than 200 classes of quasi-smooth Calabi--Yau threefolds inside weighted projective 4-space which come w…

A remarkable class of elliptic surfaces of amplitude 1 in weighted projective space
Gregory Pearlstein, Chris Peters, Appendix C by Wim Nijgh
Surfaces of amplitude 1 in ordinary projective space are of general type, but this need not be the case in weighted projective spaces. Indeed, there are 4 classes of quasi-smooth w…
