On the complexity of isomorphism problems for tensors, groups, and polynomials V: over commutative rings

Joshua A. Grochow, Youming Qiao, Katherine E. Stange +1

Tensors over commutative rings naturally appear in number theory, geometry, and group theory. For example, $2\times 2\times 2$ tensors over $\mathbb{Z}$ form the starting point of…
