Abstract:
Estimating covering functionals of convex bodies is a natural, fundamental, and difficult problem from convex and discrete geometry.The definitions of covering functionals are reviewed, the relation between estimations of covering functionals and Hadwigers covering problem are clarified,the program to attack the inequality part of Hadwigers covering conjecture which is based on estimations of covering functionals is presented, and the known results on estimations of covering functionals are surveyed.
