Normal Biconformal Spaces Normal Biconformal Spaces

A new 8-dimensional conformal gauging avoids the unphysical size change, third order gravitational field equations, and auxiliary fields that prevent taking the conformal group as a fundamental symmetry. We give the structure equations, gauge transformations and intrinsic metric structure for the new biconformal spaces. We prove that a torsion-free biconformal space with exact Weyl form, closed...

End spaces of graphs are normal

We show that the topological space of any infinite graph and its ends is normal. In particular, end spaces themselves are normal.

Normal Numbers Are Normal

A number is normal in base b if every sequence of k symbols in the letters 0, 1, . . . , b− 1 occurs in the base-b expansion of the given number with the expected frequency b−k. From an informal point of view, we can think of numbers normal in base 2 as those produced by flipping a fair coin, recording 1 for heads and 0 for tails. Normal numbers are those which are normal in every base. In this...

Why are Normal Distributions Normal?

We seem to be surrounded by bell curves—curves more formally known as normal distributions, or Gaussian distributions. All manner of things appear to be distributed normally: people’s heights, sizes of snowflakes, errors in measurements, lifetimes of lightbulbs, IQ scores, weights of loaves of bread, and so on. I argue that the standard explanation for why such quantities are normally distribut...

Examples of singular normal complex spaces which are topological manifolds.

In case V is irreducible with singular curve C, we cannot write every oeH3(W V) as a tube. Indeed, oa = 6C4 and C4 Will meet C in a finite number of points. The trouble is similar to the above and may be overcome as follows: Let DC V be a curve meeting C transversely at a finite number of points pi,...pt. For simplicity, assume t = 1, p = pi, and let B be a small ball around p in W. We may assu...
