%0 Journal Article %T Modular operads and the quantum open-closed homotopy algebra %A Martin Doubek %A Branislav Jurco %A Korbinian Muenster %J Mathematics %D 2013 %I arXiv %X We verify that certain algebras appearing in string field theory are algebras over Feynman transform of modular operads which we describe explicitly. Equivalent description in terms of solutions of generalized BV master equations are explained from the operadic point of view. %U http://arxiv.org/abs/1308.3223v2
