The concept of a singular hyperbolic attractor was introduced in 1998 by C. A. Morales, M. J. Pacífico, and E. R. Pujals [C. R. Acad. Sci., Paris, Sér. I, Math. 326, No. 1, 81–86 (1998; Zbl 0918.58036)] and D. V. Turaev and L. P. Shil’nikov [Sb. Math. 189, No. 2, 137–160 (1998); translation from Mat. Sb. 189, No. 2, 291–314 (1998; Zbl 0927.37017)]. This definition was motivated by the celebrated Lorenz system and the notion of a hyperbolic attractor. Yet another definition in terms of an invariant system of cones in the dual space has been suggested later by the author [Sb. Math. 196, No. 4, 561–594 (2005); translation from Mat. Sb. 196, No. 4, 99–134 (2005; Zbl 1101.37022)].
The purpose of this nicely written paper is to explore properties of singular hyperbolic attractors which are then used to establish existence of invariant measures of Sinaĭ-Bowen-Ruelle type for singular hyperbolic flows. One of the principal goals is to prove existence of strong unstable spaces and manifolds on a sufficiently representative set. A detailed analysis of Sinaĭ-Bowen-Ruelle invariant measures will be provided in forthcoming papers.
