TY - JOUR T1 - The Hermite-Hadamard type inequalities for the functions whose derivative is logarithmic $p$-convex function AU - Sezer, Sevda AU - Tınaztepe, Gültekin AU - Sezer Evcan, Sinem AU - Eken, Zeynep PY - 2025 DA - April Y2 - 2024 DO - 10.15672/hujms.1444589 JF - Hacettepe Journal of Mathematics and Statistics PB - Hacettepe University WT - DergiPark SN - 2651-477X SP - 404 EP - 413 VL - 54 IS - 2 LA - en AB - By means of an integral identity, several Hermite-Hadamard type inequalities are presented in this study for a function whose derivative's absolute value is the log-p-convex function. With the use of these findings, we are able to determine the boundaries in terms of elementary functions for certain specific functions, such as the imaginary error function, the exponential integral, the hyperbolic sine and cosine functions. Additionally, a relationship between beta function, the hyperbolic sine and cosine functions is stated. Through the obtained results, a bound for numerical integration of such type functions is provided.
