and USA. There were 10 invited keynote speakers, 29 contributed talks, and 10 poster presentations. This issue of BIT Numerical Mathematics contains carefully selected and refereed papers by participants who delivered oral and poster presentations at the conference.The papers discuss the HSS iteration method and its generalizations for the solution of large sparse non-Hermitian positive definite systems of linear equations [8], iterative methods and preconditioning techniques based on matrix splittings for large sparse saddle-point problems [2,3,[5][6][7]9,11], the iterated Tikhonov regularization method for the solution of large-scale Tikhonov minimization problems [4], rigorous convergence analysis of alternating variable minimization with multiplier methods for quadratic programming problems with equality constraints [1], and modeling the interaction of flow and molecular orientation in a complex fluid of nematic liquid crystals [10].The topics covered at NASC 2014 include direct and iterative methods for systems of linear and nonlinear equations; preconditioning and Krylov subspace iter-
