We introduce and study the maximal unipotent finite quotient for algebraic group schemes in positive characteristics. Applied to Picard schemes. this quotient encodes unusual torsion. We construct integral Fano threefolds where such unusual torsion actually appears. https://dutasyfhiy7m.timeblog.net/70682786/machine-learning-based-fine-classification-of-agricultural-crops-in-the-cross-border-basin-of-the-heilongjiang-river-between-china-and-russia
