Constructing Economic Summary Indexes via Principal Curves (2010)
Presentation / Conference Contribution
Zayed, M., & Einbeck, J. (2010, December). Constructing Economic Summary Indexes via Principal Curves. Presented at COMPSTAT 2010, Paris, France

Index number construction is an important and traditional subject in both the statistical and the economical sciences. A novel technique based on localized principal components to compose a single summary index from a collection of indexes is propose...

MHV diagrams in momentum twistor space (2010)
Journal Article
Bullimore, M., Mason, L., & Skinner, D. (2010). MHV diagrams in momentum twistor space. Journal of High Energy Physics, 2010(12), Article 032. https://doi.org/10.1007/jhep12%282010%29032

We show that there are remarkable simplifications when the MHV diagram formalism for N=4 super Yang-Mills is reformulated in momentum twistor space. The vertices are replaced by unity while each propagator becomes a dual superconformal ‘R-invariant’... Read More about MHV diagrams in momentum twistor space.
