Abstract

In this paper, the main aim is to introduce the class $mathcal {U}_p(lambda,alpha,beta,k_0)$ of $p$-harmonic mappings together with its subclasses $mathcal {U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p$ and $mathcal {U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p^0$, and investigate the properties of the mappings in these classes. First, we give a sufficient condition for mappings to be in $mathcal {U}_p(lambda,alpha,beta,k_0)$ and also the characterization of mappings in $mathcal {U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p$ for $max{0,frac{lambda-frac{1}{2}}{lambda+1}}leq alphaleq lambda$. Second, we consider the starlikeness of mappings in $mathcal {U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p^0$ for $max{0,frac{lambda-frac{1}{2}}{lambda+1}}leq alphaleq lambda$. Third, extreme points of $mathcal {U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p$ for $max{0,frac{lambda-frac{1}{2}}{lambda+1}}leq alphaleq lambda$ are found. The support points of $mathcal {U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p$ for $max{0,frac{lambda-frac{1}{2}}{lambda+1}}leq alphaleq lambda$ and convolution of mappings in $mathcal {U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p$ for $max{0,frac{lambda-frac{1}{2}}{lambda+1}}leq alphaleq lambda$ are also discussed.
