We define complex super Minkowski space time in 4 dimensions as the big cell inside a complex super flag manifold. The complex superconformal group acts naturally on this super flag, allowing us to interpret it as the conformal compactification of complex super Minkowski space time. We then consider real super Minkowski space time as a suitable real form of the complex version. Our methods are ...

Mg alloys have a vast usage where weight reduction is really significant since they do the features really well for materials of ultra-light weight. However, Mg is inherently a reactive metal and its alloys generally possess quite weak corrosion resistance that widely restricts their technological usages, especially in some rough service conditions. Despite, many investigations on the passive a...

Super twistor space admits a certain (super) complex structure deformation that preserves the Poincaré subgroup of the symmetry group PSL(4|4) and depends on 10 parameters. In a previous paper [hep-th/0502076], it was proposed that in twistor string theory this deformation corresponds to augmenting N = 4 super Yang-Mills theory by a mass term for the left-chirality spinors. In this paper we ana...

Let G = (V,E) be a graph of order p and size q. It is known that if G is super edge-magic graph then q ≤ 2p− 3. Furthermore, if G is super edge-magic and q = 2p− 3, then the girth of G is 3. It is also known that if the girth of G is at least 4 and G is super edge-magic then q ≤ 2p − 5. In this paper we show that there are infinitely many graphs which are super edge-magic, have girth 5, and q =...

In statistical planning of experiments, super-simple designs are the ones providing samples with maximum intersection as small as possible. Super-simple designs are also useful in constructing codes and designs such as superimposed codes and perfect hash families. The existence of super-simple (v, 4, λ)BIBDs have been determined for λ = 2, 3, 4, 5, 6. In this paper, we investigate the existence...
