A class of isoperimetric inequalities
The main aim of this paper is to obtain certain isoperimetric inequalities for a class of closed convex curves \(\Gamma\) with perimeter \(2\pi\) similar to those of \textit{H. Sachs} [Wiss. Z. Martin Luther Univ. Halle Wittenberg 8, 121-126, 127-134 (1958; Zbl 0091.356)] and \textit{R. Wegmann} [Math. Nachr. 69, 173-190 (1975; Zbl 0277.52010)].
