The classSnconsists of univalent, harmonic, and sense-preserving functionsJunit disk δ such thatwhere. Using a technique from Clinic and Shell-Small, we construct a family of I-slit mappings inSpby varying. AsW(z)changes, the tin of the slit slides along the negative real axis from the point U to - 1 In doing so. we establish that the inner mapping radiusp(f)can be as large as 4. In addition, we show that the inner mapping radius for functions incan be as small as 1/2 and as large as 2.
