Results . By a graph 1 we mean an ordered pair or = (g, G) where G C [g]2 . Let y> 0 . The sequence {G, : v < y } is said to be an edge coloring of 9 by y colors if the Gv are disjoint and their union is G . For h c g we denote by ig(h) the subgraph of I spanned by the set h i.e . 1(h) = (h, G n [ h j 2 ) . We say that the graph -41, = (h, H) can be embedded in the v-th color of the edge coloring {G,, : v < y} of G if r is isomorphic to a spanned subgraph %,(G') of !§v . We say that .M' can be strongly embedded into the v-th color if it is isomorphic to some spanned subgraph 19,,(g') such that %,(g') = 9(g') .
