We study an old variational problem formulated by Euler as Proposition 53 of his Scientia Navalis by means of the direct method of the calculus of variations. Precisely, through relaxation arguments, we prove the existence of minimizers. We fully investigate the analytical structure of the minimizers in dependence of the geometric parameters and we identify the ranges of uniqueness and non-uniqueness.

A paper of Legendre revisited
In [4] Legendre discusses the set of admissible functions for Newton's variational problem of minimal resistance. He proposes a particular side constraint to ensure existence of a solution. In the
A symmetry problem in the calculus of variations
We consider a class of integral functionals defined in a Sobolev space of functions vanishing at the boundary of a nonempty bounded connected open n-dimensional set. We prove that, if the functional
Existence of minimizers for Newton's problem of the body of minimal resistance under a single impact assumption
We prove that the infimum of Newton's functional of minimal resistanceF(u):=∫Ωdx/(1+|▽u(x)|2), where Ω ⊂R2 is a strictly convex domain, is not attained in a wide class of functions satisfying a

Consider the Newtonian potential of a homogeneous bounded body DR 3 with known constant density and connected complement. If this potential equals c/|x| in a neighborhood of infinity, where c > 0 is
The minimal resistance problem in a class of non convex bodies
We characterize the solution to the Newton minimal resistance problem in a class of radial q-concave profiles. We also give the corresponding result for one-dimensional profiles. Moreover, we provide

A survey on the Newton problem of optimal profiles
This chapter aims to present a survey on some recent results about one of the first problems in the calculus of variations, namely Newton’s problem of minimal resistance. Many variants of the problem
Newton’s aerodynamic for non-convex bodies
We characterize the solution to the Newton minimal resistance problem in a specific class of hollow profiles, satisfying a q-concavity condition. We treat two-dimensional bodies and radially
Minimizing within Convex Bodies Using a Convex Hull Method
This paper presents numerical methods to solve optimization problems on the space of convex functions or among convex bodies and gives approximate solutions better than the theoretical known ones, hence demonstrating that the minimizers do not belong to these classes.
