The conjecture states that the Mahler volume of any symmetric convex body, i.e. the product of the volume of the symmetric convex body and the volume of its dual body, is minimized by the (hyper-)cube. The conjecture was stated and solved in 1938 for the 2-dimensional case by Kurt Mahler. While the maximizer for this problem is known (it is the ball), the conjecture about the minimizer is still open for all dimensions greater than 2. A lot of effort has benn made to solve this conjecture, and many different ways to attack the conjecture, from simple geometric attempts to ones using sophisticated results from functional analysis, have all been tried unsuccesfully. We will present and discuss the most important approaches. Given the support function of the body, we will then introduce several formulas for the volume of the dual and the original body and hence for the Mahler volume. These formulas are tested for their effectiveness and used to perform numerical work on the conjecture. We examine the conjectured minimizers of the Mahler volume by approximating them in different ways. First the spherical harmonic expansion of their support functions is calculated and then the bodies are analyzed with respect to the length of that expansion. Afterwards the cube is further examined by approximating its principal radii of curvature functions, which involve Dirac delta functions. en_US dc.description.degree M.S. en_US dc.identifier.uri http://hdl.handle.net/1853/37262 dc.publisher Georgia Institute of Technology en_US dc.subject Dual body en_US dc.subject Convex geometry en_US dc.subject Mahler volume en_US dc.subject Volume product en_US dc.subject.lcsh Convex geometry dc.subject.lcsh Volume (Cubic content) dc.title Mahler's conjecture in convex geometry: a summary and further numerical analysis en_US dc.type Text dc.type.genre Thesis dspace.entity.type Publication local.contributor.advisor Harrell, Evans M. local.contributor.corporatename College of Sciences local.contributor.corporatename School of Mathematics relation.isAdvisorOfPublication f4970e81-552d-4cbb-afa2-d680962b0a59 relation.isOrgUnitOfPublication 85042be6-2d68-4e07-b384-e1f908fae48a relation.isOrgUnitOfPublication 84e5d930-8c17-4e24-96cc-63f5ab63da69
