%0 Journal Article %T Detecting bifurcation values at infinity of real polynomials %A Luis Renato G. Dias %A Mihai Tibar %J Mathematics %D 2014 %I arXiv %R 10.1007/s00209-014-1369-4 %X We present a new approach for estimating the set of bifurcation values at infinity. This yields a significant shrinking of the number of coefficients in the recent algorithm introduced by Jelonek and Kurdyka for reaching critical values at infinity by rational arcs. %U http://arxiv.org/abs/1403.6624v1
