Euler cycles and Mennicke symbols

Mrinal Kanti Das, Soumi Tikader, Md. Ali Zinna

Let $R$ be a smooth affine domain of dimension $d \geq 2$ over an infinite perfect field $k$ . We establish a morphism from the Euler class group $E^{d} (R)$ to $U m_{d + 1} (R) / E_{d + 1} (R)$ …

$P^{1}$ -gluing for local complete intersections

Mrinal Kanti Das, Soumi Tikader, Md. Ali Zinna

We prove an analogue of the Affine Horrocks' Theorem for local complete intersection ideals of height $n$ in $R [T]$ , where $R$ is a regular domain of dimension $d$ , which is essent…

From Euler class groups to Mennicke symbols and a monic inversion principle

Mrinal Kanti Das, Soumi Tikader, Md. Ali Zinna

Let $R$ be a regular domain of dimension $d \geq 2$ which is essentially of finite type over an infinite perfect field $k$ . We compare the Euler class group $E^{d} (R)$ with the van de…
