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.

1539 symbols.

h_t

h_t

13 equations

Symbol h_t: the independently measured human task horizon in active minutes, not the number of agent tool calls.

H_t

H_t

4 equations

Symbol H_t: the harvest added.

h_t^{(i)}

h^{(i)}

h^{(i)}

1 equation

Symbol h^(i): the because.

h^{(j)}

h^{(j)}

1 equation

Symbol h^(j): disjoint by construction, worker i ’s error cannot enter worker j ’s context directly — it can only reach the supervisor, and only in whatever compressed form the worker chooses to report.

h^2

I_0

I_0

8 equations

Symbol I_0: the article’s single most important number, because it is the rate at which the trait shows up in models that never touched the source at all — the convergence baseline , the rate any theory of pure coincidence has to beat.
