Symbols and notation

Symbols can mean different things in different articles. Definitions below are shown only when an equation guide or its article provides one; otherwise the entry identifies where to read the equation in context.

1506 symbols.

D_{\rm irr}

4 equations

Symbol D_rm irr: monotone.

D_{AI}

D_{AI}

1 equation

No site-wide meaning is inferred for this symbol.

d_{ij}

d_{ij}

2 equations

Distance for this branch pair: The separation between mass A on branch i and mass B on branch j. A smaller separation gives a larger gravitational interaction energy and therefore a larger accumulated phase.

D_0

D_0

6 equations

Symbol D_0: the defect density.

d_1^2

d_1^2

1 equation

No site-wide meaning is inferred for this symbol.

d_2^2

d_2^2

1 equation

No site-wide meaning is inferred for this symbol.

D_A

D_A

3 equations

Symbol D_A: the angular diameter distance to that same epoch.

d_c

d_c

3 equations

Symbol d_c: only bounded once you have already imagined the worst plausible use of the capability — the same failure of imagination that undermines defense-in-depth probability estimates generally.
