Let A be an artin algebra. An indecomposable A-module M is called weakly directing if it does not belong to a cycle of nonzero nonisomorphisms between indecomposable modules from the same component of . This paper deals with weakly directing modules. We investigate the distinctions and connections between weakly directing modules and directing modules.

Direct RF Modulation Transmitter
PROBLEM TO BE SOLVED: To provide a direct RF modulation transmitter capable of saving more power consumption. SOLUTION: The direct RF modulation transmitter comprises: a passive mixer circuit 100 which inputs digital baseband data D of 1 bit, inverted data DN, a first RF signal, and a second RF signal whose phase is different from that of the first RF ...Fukuda, Shuichi, Nauta, Bram

Infinite Direct Sums of Lifting Modules
Communications in Algebra, 2006A module M over a ring R is called a lifting module if every submodule A of M contains a direct summand K of M such that A/K is a small submodule of M/K (e.g., local modules are lifting). It is known that a (finite) direct sum of lifting modules need not be lifting.
