Abstract
In a recent publication
[D. Govc, W. A. Marzantowicz and P. Pavešić,
Estimates of covering type and the number of vertices of minimal triangulations,
Discrete Comput. Geom. 63 2020, 1, 31–48],
we have introduced a new method, based on
the Lusternik–Schnirelmann category and the cohomology ring of a space X, that yields lower bounds
for the size of a triangulation of X. In this current paper, we present an important extension
that takes into account the fundamental group of X. In fact, if
