Definitions of the relevant variables.

Symbol Equation Definition
l Level of fragmentation
Rl Spatial scale at level l
Rstop Spatial scale beyond which core fragmentation stops
i Identifies a specific child within one parent when several fragments are produced on the same scale
Ml,i 3 Mass of the i–th child at level l
Ml 7 Average mass of all fragments at the level Rl
r Scaling ratio between two successive levels
nl Number of fragments produced at level l + 1 by one parent at level l
pl(nl) Probability a parent at level l produces nl fragments at level l + 1
nl¯Mathematical equation: $\overline {{n_l}} $ 1 Expected number of fragments one parent at level l produces at the next level
ϵl 6 Mass efficiency with which fragments are formed from their parent at the previous level
ϵ¯Mathematical equation: $\overline {{_ * }} $ Average mass efficiency with which the last fragmenting cores at Rstop turn into stars
q Mass ratio between the more massive child and the less massive one within one siblinghood
ψl,i(nl, q) 4 Fraction of mass received by the i–th children from its parental reservoir ϵlMl
Γ(R, M) 12 Power-law index of a mass function in a ∂N/∂ log M representation at mass M and scale R
ϕ(M) 5 Spatial fragmentation rate
ϕMMathematical equation: $\phi _M^\prime $ Derivative of the fragmentation rate with respect to the mass
ξ(M) 6 Spatial mass transfer rate
ξMMathematical equation: $\xi _M^\prime $ Derivative of the mass transfer rate with respect to the mass
ℰ(R) Fragment formation mass efficiency between the cloud and the cores at scale R

Notes. The ‘–’ character indicates the variable is not referenced in equations since it is introduced as a definition in the text.
