      Let V be an arbitrary vector space over a field K, and let End(V) be the ring of all K-linear transformations of V. We characterize the diagonalizable linear transformations in End(V), as well as the (simultaneously) ...
    • Infinity structures and higher products in rational homotopy theory 

      Moreno Fernandez, Jose Manuel (UMA Editorial, 2018)
      Rational homotopy theory classically studies the torsion free phenomena in the homotopy category of topological spaces and continuous maps. Its success is mainly due to the existence of relatively simple algebraic models ...

    • Jordan-lie inner ideals of finite dimensional associative algebras 

      Baranov, Alexander (2017-06-15)
      Any associative ring A becomes a Lie ring A(−) under [x, y] = xy−yx. Let A(1) = [A, A] be the derived subalgebra of A(−) and let Z be its center. In the early 1950s Herstein initiated a study of Lie ideals of A in case ...
