    "abstract": "These lecture notes cover the important developments in histories approach to\nquantum mechanics with overall content and emphasis somewhat different from\nother reviews and books on the subject.The idea of Houtappel, Van Dam and\nWigner of employing objects based on primitive concepts of physical theories is\ndiscussed in some detail and the fact that histories are such objects is\nemphasized. Application of histories formalism to the problem of understanding\nthe quasiclassical domain is treated in some detail. Other topics discussed\ninclude generalized histories-based quantum mechanics and its application to\nthe quantum mechanics of space-time,generalization of the notion of time\nsequences employing partial semigroups,quasitemporal structures, history\nprojection operator (HPO) formalism, the algebraic scheme of Isham and Linden,\nan axiomatic scheme for quasitemporal histories-based theories and symmetries\nand conservation laws in histories-based theories.",
