Applications of Swan's Bertini to unimodular rows

Manoj K. Keshari, Sampat Sharma

Let $R$ be an affine algebra of dimension $d \geq 4$ over a perfect field $k$ of char $\neq = 2$ and $I$ be an ideal of $R$ . Then - Um $_{d + 1} (R, I) / E_{d + 1} (R, I)$ has nice group s…

K_0 of hypersurfaces defined by x_1^2+ ... + x_n^2 = \pm 1

Manoj K Keshari, Satya Mandal

Let $k$ be a field of characteristic $\neq = 2$ and let $Q_{n, m} (x_{1}, ..., x_{n}, y_{1}, ..., y_{m}) = x_{1}^{2} + ... + x_{n}^{2} - (y_{1}^{2} + ... + y_{m}^{2})$ be a quadratic form over $k$ . Let $R(Q_{n,m})=R_{n,m…
