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:

    What journeyings on foot and on horseback through the wilderness, to preach the gospel to these minks and muskrats! who first, no doubt, listened with their red ears out of a natural hospitality and courtesy, and afterward from curiosity or even interest, till at length there “were praying Indians,” and, as the General Court wrote to Cromwell, the “work is brought to this perfection that some of the Indians themselves can pray and prophesy in a comfortable manner.”
    Henry David Thoreau (1817–1862)

    I repeat, sir, that in whatever position you place a woman she is an ornament to society and a treasure to the world. As a sweetheart, she has few equals and no superiors; as a cousin, she is convenient; as a wealthy grandmother with an incurable distemper, she is precious; as a wet-nurse, she has no equal among men. What, sir, would the people of the earth be without woman? They would be scarce, sir, almighty scarce.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
