On the Chebyshev polynomial coefficient problem of biBazilevič functions
(Işık University Press, 2020)A function said to be biBazilevič in the open unit disk U if both the function and its inverse are Bazilevič there. In this paper, we will study a newly constructed class of biBazilevič functions. Furthermore, we establish ... 
Bishop’s property (β) and weighted conditional type operators in kquasi class A*n
(Işık University Press, 2020)An operator T is said to be kquasi class A*n operator if T*ᵏ (Tⁿ⁺¹²/ⁿ⁺¹− T*² ) Tᵏ ≥ 0, for some positive integers n and k. In this paper, we prove that the kquasi class A*n operators have Bishop, s property (β). Then, ...
