Abstract The book “Handbook of Finsler geometry” has been included with a CD containing an elegant Maple package, FINSLER, for calculations in Finsler geometry. Using this package, an example concerning a Finsler generalization of Einstein’s vacuum field equations was treated. In this example, the calculation of the components of the hv-curvature of Cartan connection leads to wrong expressions. On the other hand, the FINSLER package works only in dimension four. We introduce a new Finsler package in w... Title of program: Finsler Catalogue Id: AERE_v1_0 Nature of problem The FINSLER package [2] (included with [1]) has some problems: the wrong calculations of the hv-curvature components of Cartan connection and the non-ability of computing some curvature tensors in dimensions different from four. Moreover, it computes some geometric objects in a non-simplified form. Versions of this program held in the CPC repository in Mendeley Data AERE_v1_0; Finsler; 10.1016/j.cpc.2013.10.024 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
