The Landau-type theorems for functions with logharmonic Laplacian and bounded length distortions
Sudip Kumar Guin, Rajib Mandal
In this study, we establish certain Landau-type theorems for functions with logharmonic Laplacian of the form , , where is logharmonic and is ha…
On meromorphic solutions of certain Fermat-type difference and analogues equations concerning open problems
Rajib Mandal, Raju Biswas, Sudip Kumar Guin
In this paper, we have found that some certain Fermat-type shift and difference equations have the meromorphic solutions generated by Riccati type functions. Also we have solved th…
Entire functions of several complex variables satisfying certain Fermat-type PDDEs
Hong Yan Xu, Rajib Mandal, Raju Biswas
In this paper, we solve certain Fermat-type partial differential-difference equations for finite order entire functions of several complex variables. These results are significant…
