DESCRIPTION:Title: ON STAR-CONVEX BODIES WITH ROTATIONALLY INVARIANT SECTIO
 NS \n\nAbstract: We will outline the proof that an origin-symmetric star-c
 onvex body K with sufficiently smooth boundary and such that every hyperpl
 ane section of K passing through the origin is a body of affine revolution
 \, is itself a body of affine revolution. This will give a positive answer
  to the question asked by G. Bor\, L. Hernández-Lamoneda\, V. Jiménez de S
 antiago\, and L. Montejano-Peimbert in their recent paper on the isometric
  Banach’s conjecture\, though with slightly different prerequisites. The t
 heorem may be also seen as a high-dimensional variant of Bezdek’s conjectu
 re. Our argument is built mainly upon the tools of differential geometry a
 nd linear algebra\, but occasionally we will need to use some more involve
 d facts from other fields like algebraic topology or commutative algebra\n
