Yarı-Asal Halkalarda Ortogonal Yarı-Türevler Üzerine
Özet. Bu makalede, " bir torsion free yarı-asal halka, ve örten fonksiyonu ile belirlenmiş sıfırdan farklı iki yarı-türev olmak üzere ve ın ortogonal olması için gerek ve yeter koşul i) ii) iii) her için iv) fonksiyonu ile belirlenmiş bir yarı-türevdir, koşullarından herhangi birinin sağlanmasıdır" ve ayrıca "her için i) , ii) , iii) koşullarından birini sağlayan halkası sıfırdan farklı bir merkezil ideal kapsar" teoremleri gösterilmiştir.Anahtar Kelimeler: Yarı-türevler, ortogonal türevler, yarı-asal halkalar Abstract. In this paper, it is shown that if is torsion free semiprime ring, and are semiderivations associated with a surjective function of , and are orthogonal semiderivations if and only if the following conditions are satisfied i) ii) iii) , iv) is a semiderivation associated with a function. Also, it is proved that if i) , ii) , iii) conditions are satisfied for all then contains a nonzero central ideal.Keywords: Semi-derivations, orthogonal derivations, semi-prime rings
