چکیده
A Fano problem consists of enumerating linear spaces a fixed dimension on variety, generalizing the classical 27 lines cubic surface. Those problems with finitely many have an associated Galois group that acts these and controls complexity computing them in suitable coordinates. These groups were first defined studied by Jordan, who particular considered P3 Recently, Hashimoto Kadets determined for special family showed all other contains alternating group. complete classification rests determination groups. We use computational tools to prove several moderate size equal symmetric group, each which previously unknown.

Computing Pro-P Galois Groups
We describe methods for explicit computation of Galois groups of certain tamely ramified p-extensions. In the finite case this yields a short list of candidates for the Galois group. In the infinite case it produces a family or few families of likely candidates.
متن کاملComputing Galois Groups with Generic Resolvent Polynomials
Given an arbitrary irreducible polynomial f with rational coefficients it is difficult to determine the Galois group of the splitting field of that polynomial. When the roots of f are easy to calculate, there are a number of “tricks” that can be employed to calculate this Galois group. If the roots of f are solvable by radicals, for example, it is often easy to calculate by hand the Q-fixing au...
متن کاملAn algorithm for computing invariants of differential Galois groups’
This paper presents an algorithm to compute invariants of the differential Galois group of linear differential equations L(y) = 0: if V(L) is the vector space of solutions of L(y) = 0, we show how given some integer m, one can compute the elements of the symmetric power Sym”‘( V(L)) that are left fixed by the Galois group. The bottleneck of previous methods is the construction of a differential...
متن کاملComputing Galois Groups of Completely Reducible Differential Equations
At present we do not know a general algorithm that will compute the Galois group of a linear differential equation with coefficients in a differential field k, even when k = Q̄(x), where Q̄ is the algebraic closure of the rational numbers. In contrast, algorithms for calculating the Galois group of a polynomial with coefficients in Q or Q̄(x) have been known for a long time (van der Waerden, 1953;...
متن کاملGalois groups of Schubert problems via homotopy computation
Numerical homotopy continuation of solutions to polynomial equations is the foundation for numerical algebraic geometry, whose development has been driven by applications of mathematics. We use numerical homotopy continuation to investigate the problem in pure mathematics of determining Galois groups in the Schubert calculus. For example, we show by direct computation that the Galois group of t...
