(Eingegangen am 22. 11. 1979) REES matrix semigroups &I= (S, ,I, -1, P) over a semigroup correspond loosely to the n X n matrix rings over it ring R. It is well known that &(R,)x .=(&(R)),,. Moreover, when S is it finite BRANDT semigroup, S

Poly-Schiff base containing bisthiazole rings (TAPDA) has been prepared from terephthalaldehyde and 2,2 -diamino-4,4-bisthiazole. It was found that the TAPDA polymer film is permeable to H 2 , O 2 , and N 2 and can be converted into an electrical conductor by pyrolysis at high temperature in nitroge
I prove that given a finite semigroup or finite associative ring S and a system โบ of equations of the form ax s b or xa s b, where a, b g S, x is an unknown, it is algorithmically impossible to decide whether or not โบ is solvable over S, that is, ลฝ whether or not there exists a bigger semigroup or r
The theory of rings of quotients of a given ring has been developed by many authors including Asmo [ l ] , JOHNSON [6], UTUMI [ l l ] , and STENSTEOM [lo]. A corresponding theory of semigroups of quotients has been studied by BERTHUUME [3], MOMORRIS [8], and &KLE [6]. LUEDEMAN [7] has begun the deve
