On Boolean Lattices of Module Classes

Some properties of and relations between several （big） lattices of module classes are used in this paper to obtain information about the ring over which modules are taken. The authors reach characterizations of trivial rings, semisimple rings and certain rings over which every torsion theory is hereditary.

一些性质和在几之间的关系(大) 模块班的格子在这份报纸被使用关于模块在上被拿的戒指获得信息。作者到达每个扭转理论在上是世袭的小戒指， semisimple 戒指和某些戒指的描述。
