Annamalai Ramanathan
Annamalai Ramanathan, Indian mathematician (Madras 29 August 1946 – Chicago 12 March 1993) Gave a notion of stability for principal G-bundle on a Riemann surface Constructed a moduli space for semistable principal bundles with a real reductive structure group With S. Ramanan proved that the tensor product of a semistable vector bundles is semistable (1984) With V.B. Mehta introduced the notion of a Frobenius split variety and compatibly split subvarieties (1985) Proved that a principal G-bundle admits an Einstein-Hermitian connection if and only if it is polystable (1988) EPONYMY Ramanan-Ramanathan theorem Rumford-Mehta-Ramanathan restriction theorem Raghunathan-Ramanathan theorem Kumar-Narasimhan-Ramanathan lemma Ramanathan lemma Ramanathan stability Mehta-Ramanathan theorem for linear systems Mehta-Ramanathan theorem for slope K-semistability Mehta-Ramanathan theorem rank of a real form

André Pinto Rebouças, Brazilian engineer (Cachoeira, Bahia State 13 January 1838 – Funchal, Madeira Island 09 May 1898) ACHIEVEMENTS Suggested multiple docks (1863) Developed a kind of torpedo in time of war against Paraguay Published an incomplete monograph “Ensaio de um vocabulário technico da arte de construir e das sciencias accessorias, nas línguas franceza, ingleza e nacional” (1867-8), with which aided to elaborate an engineering’s technical terminology.
