On meromorphic solutions of certain type of difference equations
We mainly discuss the existence of meromorphic (entire) solutions of certain type of non-linear difference equation of the form: $f(z)^m+P(z)f(z+c)^n=Q(z)$, which is a supplement of previous results in [K. Liu, L. Z. Yang and X. L. Liu, Existence of entire solutions of nonlinear difference equations, Czechoslovak Math. J. 61 (2011), no. 2, 565--576, and X. G. Qi...
متن کاملThe Serre Problem on Certain Bounded Domains
We give some new examples for which the Serre problem is solvable by using invariant pseudodistances.
متن کاملA note on the socle of certain types of f-rings
For any reduced commutative $f$-ring with identity and bounded inversion, we show that a condition which is obviously necessary for the socle of the ring to coincide with the socle of its bounded part, is actually also sufficient. The condition is that every minimal ideal of the ring consist entirely of bounded elements. It is not too stringent, and is satisfied, for instance, by rings of ...
متن کاملOn K. F. Roth’s ‘On Certain Sets of Integers’
The aim of this paper is to inspect [6] and work through to make every step transparent and clear. Main Result From [6] In [6] Roth looked at three term arithmetic sequences in certain sets of integers. He considered a function, called A(x), that was the maximum size of a subset of {1, 2, . . . , x} that avoided three term arithmetic sequences. Having already proven the main result: A(x) x −→ 0...
متن کاملOn Certain Analytic Functions of Bounded Boundary Rotation
In this paper we introduce certain analytic functions of boundary rotation bounded by k1r which are of Caratheodory origin. With them we study two classes of analytic and univalent functions in the unit disk E = {z E C Izi < I} , which are also of bounded boundary rotation.
