Solution by step functions of a minimum problem in L2[0,T], using generalized h- and g-indices
作者:
Highlights:
• Generalized h- and g-indices are studied.
• It is shown that the h-index is a special case of the g-index.
• These indices are applied to solve a minimum problem in L2.
• Using step functions, this minimum problem is solved for decreasing functions.
• Results are applied to the case of Lotkaian informetrics (Zipf, Lotka).
