Abstract

This survey mainly deals with the tilted Carath{\'e}odory class by angle λ\lambda (denoted by Pλ\mathcal{P}_{\lambda}) an element of which maps the unit disc into the tilted right half-plane {w:eiλw>0}\{w: \Re e^{i\lambda} w>0\}. Firstly we will characterize Pλ\mathcal{P}_{\lambda} from different aspects. In section 3, various estimates of functionals over Pλ\mathcal{P}_{\lambda} are deduced from the known corresponding estimates of P0\mathcal{P}_{0} or elementary functional analysis. Finally some subsets of analytic functions related to Pλ\mathcal{P}_{\lambda} including close-to-convex functions with argument λ\lambda, λ\lambda-spirallike functions, λ\lambda-Robertson functions and analytic functions whose derivative is in Pλ\mathcal{P}_{\lambda} are also considered as applications
