A. Singh Institute of Mathematical Sciences, C.I.T. Chennai, India anupamk18@gmail.com Real elements in algebraic groups Let G be an algebraic group defined over a field k . ... Let G be a connected semisimple algebraic group of adjoint type defined over a perfect field k . ... It follows that if G is connected semisimple of adjoint type, with -1 in its Weyl group, then every semisimple element in G(k ) is strongly real in G(k ). This also shows that any regular element in such a group is real. ...
