Some remarks on $u$ - $S$ -Noetherian and $u$ - $S$ -coherent rings

Xiaolei Zhang, Wei Qi

In this paper, we give some new characterizations of $u$ - $S$ -Noetherian rings and $u$ - $S$ -coherent rings in terms of uniform $S$ -version of injective precovers, flat preenvelopes a…

A note on pure-semisimple rings

Xiaolei Zhang, Wei Qi

In this note, we give several characterizations of left pure-semisimple in terms of the (pre)envelope, (pre)cover, direct limits, direct sums, inverse limits and direct products pr…
