METRIC ENTROPY FOR FUNCTIONS OF BOUNDED TOTAL GENERALIZED VARIATION

SIAM JOURNAL ON MATHEMATICAL ANALYSIS, 53(1), 1168–1190.

By: R. Capuani, P. Dutta* & K. Nguyen

author keywords: metric entropy; doubling dimension; total generalized variation
TL;DR: A sharp estimate is established for a minimal number of binary digits needed to represent all bounded total generalized variation functions taking values in a general totally bounded metric space up to an accuracy of $\varepsilon>0$ with respect to the ${\bf L}^1$-distance.
