Complete Intersection - General Position

General Position

For more refined questions, the nature of the intersection has to be addressed more closely. The hypersurfaces may be required to satisfy a transversality condition (like their tangent spaces being in general position at intersection points). The intersection may be scheme-theoretic, in other words here the homogeneous ideal generated by the Fi(X0, ..., Xn) may be required to be the defining ideal of V, and not just have the correct radical. In commutative algebra, the complete intersection condition is translated into regular sequence terms, allowing the definition of local complete intersection, or after some localization an ideal has defining regular sequences.

Famous quotes containing the words general and/or position:

    We all have known
    Good critics, who have stamped out poet’s hopes;
    Good statesmen, who pulled ruin on the state;
    Good patriots, who, for a theory, risked a cause;
    Good kings, who disembowelled for a tax;
    Good Popes, who brought all good to jeopardy;
    Good Christians, who sat still in easy-chairs;
    And damned the general world for standing up.—
    Now, may the good God pardon all good men!
    Elizabeth Barrett Browning (1806–1861)

    All conservatives are such from personal defects. They have been effeminated by position or nature, born halt and blind, through luxury of their parents, and can only, like invalids, act on the defensive. But strong natures, backwoodsmen, New Hampshire giants, Napoleons, Burkes, Broughams, Websters, Kossuths, are inevitable patriots, until their life ebbs, and their defects and gout, palsy and money, warp them.
    Ralph Waldo Emerson (1803–1882)
