摘要 受Lutwak与Petty工作[25-26,37]的启发,该文构造了关于给定凸体K的一类新型星体gK,建立了关于gK的等周不等式,并由此给出关于凸体K的逆Bonnesen-型等周不等式. Motivated by works of Lutwak and Petty[25-26,37],a new star body GK associated with a given convex body K is constructed.The isoperimetric inequality for GK and the reverse Bonnesen-style inequalities for K are established.
