## Abstract The __crossing number__, cr(__G__), of a graph __G__ is the least number of crossing points in any drawing of __G__ in the plane. According to the Crossing Lemma of M. Ajtai, V. Chvátal, M. Newborn, E. Szemerédi, Theory and Practice of Combinatorics, North‐Holland, Amsterdam, New York,

## Abstract Crossing numbers of Sierpiński graphs __S__(__n__,__k__) and their regularizations __S__^+^(__n__,__k__) and __S__^++^(__n__,__k__) are studied. Drawings of these graphs are presented and proved to be optimal for __S__^+^(__n__,__k__) and __S__^++^(__n__,__k__) for every __n__ ≥ 1 and _
## Abstract We describe a method of creating an infinite family of crossing‐critical graphs from a single small planar map, the __tile__, by gluing together many copies of the tile together in a circular fashion. This method yields all known infinite families of __k__‐crossing‐critical graphs. Furt
## Abstract In an earlier paper 3, we studied cycles in graphs that intersect all edge‐cuts of prescribed sizes. Passing to a more general setting, we examine the existence of __T__‐joins in grafts that intersect all edge‐cuts whose size is in a given set __A__ ⊆{1,2,3}. In particular, we character
## Abstract Results giving the exact crossing number of an infinite family of graphs on some surface are very scarce. In this paper we show the following: for __G__ = __Q__~__n__~ × __K__~4.4~, cr~__y__(__G__)‐__m__~(__G__) = 4__m__, for 0 ⩽ = __m__ ⩽ 2^__n__^. A generalization is obtained, for cer
