Packing 4-Partite Tree into Complete 4-Partite Graph

For graphs G and H , an embedding of G into H is an injection see formula in PDF such that see formula in PDF whenever see formula in PDF. A packing of p graphs see formula in PDF into see formula in PDFis a p -tuple see formula in PDF such that, for see formula in PDF, see formula in PDF is an embedding of see formula in PDF into H and the p sets see formula in PDF are mutually disjoint. Motivated by the "Tree Packing Conjecture" made by Gysee formula in PDFrfsee formula in PDFs and Lehel, Wang Hong conjectured that for each k -partite tree, there is a packing of two copies of see formula in PDF into a complete k -partite graph see formula in PDF, where see formula in PDF. In this paper, we confirm this conjecture for see formula in PDF.
