零点のない領域の英語

複素領域Ｄに零点を持つ一変数実多項式のうち、領域Ｄに零点を持たない一変数実多項式ｆに最も近い一変数実多項式ｆ~と、一変数実多項式ｆとのｌ^∞-ノルムで定義された距離を、最悪の場合であっても多項式時間の計算量で求める。例文帳に追加

To find a distance defined by a 1^∞-norms of a single variable polynomial f~ nearest to a single variable real polynomial f not having a zero point in a complex area D, and the single variable real polynomial f, out of the single variable real polynomials having the zero point in the area D, in a time for calculating a polynomial time at worst. - 特許庁

複素区間多項式Ｆ（ｘ）中に、領域Ｄに零点を持たない多項式が存在する場合に、領域Ｄの境界Ｃ上の一点ｃ（代表点ｃ）を選択して、この代表点ｃを零点とする多項式が複素区間多項式Ｆ（ｘ）の中に存在するか否かを調べる（ステップＳ４）。例文帳に追加

If a polynomial having no zero point in an area D exists in a complex interval polynomial F(x), one point c (representative point c) on the boundary C of the area D is selected and a check is made as to whether or not a polynomial whose zero point is the representative point c exists in the complex interval polynomial F(x) (step S4). - 特許庁
