The Chow Characteristic Image of \(\Spin(10)\) via the Affine Cone over the Spinor Variety
Sanghoon Baek
Let \(G=\Spin(10)\) be the split spin group over a field of characteristic different from \(2\), and let \(T\subset G\) be a split maximal torus. We determine the image of the inte…

Integral Weyl Invariants in Chow Characteristic Images of Spin and Special Clifford Groups
Sanghoon Baek
Let $G=\Spin(n)$ be the split spin group over an arbitrary field, with . Extending a Steenrod-theoretic obstruction of Karpenko, we classify the recursively defined integral…
