Abstract
A vertex v in a map M has the face-sequence \((p_1^{n_1}. p_2^{n_2}. \ldots . p_k^{n_k})\), if consecutive \(n_i\) numbers of \(p_i\)-gons are incident at v in the given cyclic order for \(1 \le i \le k\). A map is called semi-equivelar if the face-sequence of each vertex is same throughout the map. A doubly semi-equivelar map is a generalization of semi-equivelar map which has precisely 2 distinct face-sequences. In this article, we determine all the types of doubly semi-equivelar maps of combinatorial curvature 0 on the Klein bottle. We present classification of doubly semi-equivelar maps on the Klein bottle and illustrate this classification for those doubly semi-equivelar maps which comprise of face-sequence pairs \(\{(3^6), (3^3.4^2)\}\) and \(\{(3^3.4^2), (4^4)\}\).
