Fourth Hankel and Toeplitz determinants for bounded turning functions subordinate to 1+tanhzK. Yakaiah, R. Bharavi Sharma, K. Ganesh and K. SarojaThe aim of the present paper is to find the fourth Hankel and Toeplitz determinants for bounded turning functions subordinate to 1+tanhz. We also consider this problem for Fekete-Szego inequality and Zalcman Conjectures for bounded turning functions subordinate to 1+tanhz.Advanced Studies: Euro-Tbilisi Mathematical Journal, Vol. 16(3) (2023), pp. 1-9 |
