摘要:

LetRbe a near-ring and Mn(R) the associated near-ring ofnxnmatrices as defined by Meldrum and van der Walt. IfRiss-primitive, thenMn(R) iss-primitive. On the other hand ifMn(R) iss-primitive, then thes-radicalJs(R) is zero. With suitable chain conditions r is a faithfulMn(R)-group of type-s if and only if isMn(R)-isomorphic toGnforGa faithfulR-group oftype-s.

摘要:

Consider a setVofR-submodules ofRn,Ra commutative ring. We provide a sufficient condition onVsuch that the ring of allR-endomorphisms ofRn, which leave everyR-submodule inVinvariant, is a structural matrix ring. We also obtain results suggesting strongly that the mentioned condition is necessary too in caseRis a field.

摘要:

The asymptotic behaviour of the digits anand enof continued fractions with odd partial quotients is investigated in the context of dependence with complete connections. In particular, we obtain a formula for the geometric mean of partial denominators and the relative frequency of a pair(a, ε)of digits.
