In science:

The algebra Aλ (D , SW ) is called the generalized twisted double in [DY].
Module categories of simple current extensions of vertex operator algebras
In order to show that this field admits a functionally generic null singularity, we proceed as follows: Let x, y , u, v be the standard, double-null, Minkowski coordinates (i.e. such that ds2 = −4dudv + dx2 + dy 2 ).
How generic are null spacetime singularities?
Sensitivity to the enhancement Figure 10 shows the double-differential D0 cross section, d2σD /dpD T dy , in |y | < 1 as a function of the transverse momentum.
Heavy Quarks: Summary Report
For every 0 ≤ y ≤ x < z , we can write P[V (T (x)−) ∈ dy , V (T (x)) ∈ dz ] = U (dy )µ(dz − y ). (For a proof of this intuitively obvious claim see p. 76 of [Ber96].) Define now At(x) = x−1V (T (tx)−) and consider its “double” Laplace transform ˜A(q , λ) = Z ∞ e−qtE[exp(−λAt (x))] dt.
Dynamics of trap models
Some time ago, Lam and Tung derived a relation , similar to the Callan-Gross relation in deep-inelastic scattering, which states that the longitudinal helicity amplitude WL for the virtual photon in the DY process is exactly twice as large as the double spin-flip amplitude W∆∆ .
