A bijection between the indecomposable summands of two multiplicity free tilting modules
Gabriella D'Este, H. Melis Tekin Akcin
We show that there is a reflection type bijection between the indecomposable summands of two multiplicity free tilting modules and . This bijection fixes the common indecomp…

An analogue of Amitsur's property for the ring of pseudo-differential operators
H. Melis Tekin Akcin
Let R be a ring with a derivation δ. In this paper, we prove that an analogue of Amitsur's property holds for left T-nilpotent radideals of pseudo-differential operator rings R((x^…

On symmetric property of skew polynomial rings
Fatma Kaynarca, H. Melis Tekin Akcin
Symmetric rings were introduced by Lambek to extend usual commutative ideal theory in noncommutative rings. In this paper, we study symmetric rings over which Ore extensions are sy…
