Samir Amin : intellectuel organique au service de l'emancipation du sud
No full textThis book on Professor Samir Amin retraces his family origins, intellectual itinerary, political struggles as well as his experience in economic policy formulation in Egypt, Mali and many other countries. The fundamentals which shaped Samir Amin's thinking, directed his life-long work and influenced his action spawned from his early discovery in high school of Marxism and Historical Materialism, used as a scientific analysis of the history of human societies. This book also highlights Samir Amin's invaluable contribution to the struggle against capitalism through his indefatigable fight to deconstruct the concepts that are used to disguise the true face of historical capitalism, which is nothing but an unabashed pursuit for accumulation and dispossession of dominated countries and peoples. Through a series of interviews with Samir Amin, the author unravels the poignant and great ideas which have been at the heart of his intellectual and political fight for the last half century. The author also provides a selection of texts which includes an exhaustive bibliography, with all published writings of Samir Amin in French. This rich work is meant for a large readership - students, researchers, teachers, political leaders and citizens who are interested in the phenomenon of globalisation and its impact on the so-called 'under-developed countries

Dynamic Planar Embedding Is in DynFO
No full textPlanar Embedding is a drawing of a graph on the plane such that the edges do not intersect each other except at the vertices. We know that testing the planarity of a graph and computing its embedding (if it exists), can efficiently be computed, both sequentially [John E. Hopcroft and Robert Endre Tarjan, 1974] and in parallel [Vijaya Ramachandran and John H. Reif, 1994], when the entire graph is presented as input.
In the dynamic setting, the input graph changes one edge at a time through insertion and deletions and planarity testing/embedding has to be updated after every change. By storing auxilliary information we can improve the complexity of dynamic planarity testing/embedding over the obvious recomputation from scratch. In the sequential dynamic setting, there has been a series of works [David Eppstein et al., 1996; Giuseppe F. Italiano et al., 1993; Jacob Holm et al., 2018; Jacob Holm and Eva Rotenberg, 2020], culminating in the breakthrough result of polylog(n) sequential time (amortized) planarity testing algorithm of Holm and Rotenberg [Jacob Holm and Eva Rotenberg, 2020].
In this paper we study planar embedding through the lens of DynFO, a parallel dynamic complexity class introduced by Patnaik et al [Sushant Patnaik and Neil Immerman, 1997] (also [Guozhu Dong et al., 1995]). We show that it is possible to dynamically maintain whether an edge can be inserted to a planar graph without causing non-planarity in DynFO. We extend this to show how to maintain an embedding of a planar graph under both edge insertions and deletions, while rejecting edge insertions that violate planarity.
Our main idea is to maintain embeddings of only the triconnected components and a special two-colouring of separating pairs that enables us to side-step cascading flips when embedding of a biconnected planar graph changes, a major issue for sequential dynamic algorithms [Jacob Holm and Eva Rotenberg, 2020; Jacob Holm and Eva Rotenberg, 2020]
