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.

CLCC_{\mathrm{LC}}

C_{\mathrm{LC}}

3 equations

No site-wide meaning is inferred for this symbol.
