报告摘要：

The classical isoperimetric problem is to determine a plane figure of the largest possible area with boundary of a given length and it was known in Ancient Greece. However, the first mathematically rigorous proof was obtained only in the 19th century by Weierstrass (based on works of Bernoulli, Euler, Lagrange).

Another well-known problem in differential geometry is Minkowski problem. The Minkowski problem in integral and convex geometry becomes a hot topic recently.

We recently obtained the sharp convex mixed Lorentz-Sobolev inequality and proved that it is equivalent to a new Minkowski inequality in integral and convex geometry. These new inequalities obtained are closely related to isoperimetric problem and Minkowski problem in integral and convex geometry.
