The analytic functions, mapping the open unit disk onto petal and oval type regions, introduced by Noor and Malik (Comput. Math. Appl. 62:2209-2217, 2011), are considered to define and study their associated close-to-convex functions. This work includes certain geometric properties like sufficiency criteria, coefficient estimates, arc length, the growth rate of coefficients of Taylor series, integral preserving properties of these functions.
努尔和马利克（《计算机数学及其应用》62:2209 - 2217，2011年）引入的将单位开圆盘映射到花瓣型和卵形区域的解析函数，被用于定义和研究它们相关的近于凸函数。这项工作包括某些几何性质，如充分性准则、系数估计、弧长、泰勒级数系数的增长率以及这些函数的积分保持性质。
