A class of inequalities related to the angle bisectors and the sides of a triangle.
A generalization of a two triangle inequality.
A geometric inequality involving a mobile point in the place of the triangle.
A geometric inequality of the generalized Erdős-Mordell type.
A method for establishing certain trigonometric inequalities.
A new geometric inequality.
A pair of general triangle inequalities.
A proof of two conjectures related to the Erdős-Debrunner inequality.
A sharpening of a discrete analog of Wirtinger's and isoperimetric inequalities
A sharpening of a discrete case of Wirtinger's inequality is given. It is then used to sharpen the isoperimetric unequality for polygons.
A weighted geometric inequality and its applications.
An eigenvalue problem with mixed boundary conditions and trace theorems.
An equivalent form of the fundamental triangle inequality and its applications.
An extension of the Erdős-Debrunner inequality to general power means.
An optimal relative isoperimetric inequality in concave cylindrical domains in .
