The lambda-dimension of commutative arithmetic rings

Francois Couchot

It is shown that every commutative arithmetic ring $R$ has $l amb d a$ -dimension $l e q 3$ . An example of a commutative Kaplansky ring with $l amb d a$ -dimension 3 is given. If $R$ satis…

Local rings of bounded module type are almost maximal valuation rings

Francois Couchot

It is shown that every commutative local ring of bounded module type is an almost maximal valuation ring.
