https://doi.org/10.1007/978-1-4614-3532-7In this chapter we study latin squares and their orthogonality, and construct magic squares. We also discuss Hall’s theorem on systems of distinct representatives and apply it to latin squares and bipartite graphs. Finally, we show how complete sets of orthogonal latin squares lead to affine planes.

The subject matter provides nice connections with latin squares and edge colourings of graphs, and also provides an introduction to the ideas of block designs and resolvability which will be studied further in the final chapter. So the chapter is an exposition of interrelations be

This review will highlight current perspectives on the phylogenetic relationships between eIF2α kinases, the central structural and functional roles of their regulatory domains in the mechanisms regulating translational control, and how these eIF2α kinase family members e
