On second-order differential subordination for certain meromorphically multivalent functions
A new class $\mathcal{R}_n(A,B,\lambda)$ of meromorphically multivalent functions defined by the second-order differential subordination is introduced. Several geometric properties of this new class are studied. The sharp upper bound on $|z|=r<1$ for the functional $\mathrm{Re}\{(\lambda-1)z...
