Abstract
In this paper, we show how to extend Voronov's construction of L∞-structures by using the splitting of a graded Lie algebra into the direct vector space sum of two subalgebras, of which one is abelian, to just a graded Lie algebra inclusion without an algebraic complement. The construction uses certain Verma modules of the universal enveloping algebra of the graded Lie algebra, and it is fairly explicit in terms of convolution formulas. Voronov's result [J. Pure Appl. Algebra 202 (2005), 133–153] and Bandiera's result on nonabelian complements [http://arxiv.org/abs/1304.4097] occur as particular cases.
First of all it is a great pleasure for me to dedicate this work to Otto Kegel's 80th birthday: he was the supervisor of my master thesis in mathematics, and by his enormous patience, generosity, encouragement and his way of combining ease and utmost precision in his teaching he helped me find my way out of theoretical physics (for which I had been even less talented) towards mathematics. I should also like to thank Yaël Frégier for stimulating discussions and his well-written habilitation thesis which inspired me a lot.
