    <title language="eng">Maximal Quadratic-Free Sets</title>
    <abstract language="eng">The intersection cut paradigm is a powerful framework that facilitates&#13;
the generation of valid linear inequalities, or cutting planes, for a potentially complex set S. The key ingredients in this construction are a&#13;
simplicial conic relaxation of S and an S-free set: a convex zone whose&#13;
interior does not intersect S. Ideally, such S-free set would be maximal&#13;
inclusion-wise, as it would generate a deeper cutting plane. However, maximality can be a challenging goal in general. In this work, we show how&#13;
to construct maximal S-free sets when S is defined as a general quadratic&#13;
inequality. Our maximal S-free sets are such that efficient separation of&#13;
a vertex in LP-based approaches to quadratically constrained problems is&#13;
guaranteed. To the best of our knowledge, this work is the first to provide&#13;
maximal quadratic-free sets.</abstract>
