That would be a change and might discommode some old-time users, but I bet few would notice. We could say, pasting above the last line merely edits the log, while pasting into the last line executes all sentences ended by LF. That is a very small change from the current behavior. hhr On 7/31/2024 11:32 AM, bill lam wrote:
The Hilbert curve (also known as the Hilbert space-filling curve) is a continuous fractal space-filling curve first described by the German mathematician David Hilbert in 1891, as a variant of the space-filling Peano curves discovered by Giuseppe Peano in 1890. Because it is space-filling, its Hausdorff dimension is 2 (precisely, its image is the unit square, whose dimension is 2 in any definition of dimension; its graph is a compact set homeomorphic t… WebDec 24, 2016 · A Hilbert Curve is a type of space-filling curve, and it basically maps a line to a plane. Each point in the line corresponds to just one point in the plane, and each point in …
WebApr 18, 2024 · The Quot scheme in question parametrizes quotient sheaves of O_X^d of length n supported at p, where p is a cusp singularity on a curve X; the Hilbert scheme is the special case d=1. Our method is based on a stratification given by Gröbner bases for power series ring (a.k.a. standard bases).
