BH 15:3540. CELD ID 21524 Abstract Jewish time can be seen as a unity form several perspectives. Past, present, and future coexist and influence each other, primarily through tshuvah (return, or repentance). By doing tshuvah, a Jew's current regret for past actions retroactively affects and transforms his past, either lessening the effects of misdeeds or transforming them into merits. The Lubavitcher Rebbe teaches a more complex model, in which the potential for tshuvah is already present in the past misdeed. Thus, the past implicity influences the future, and when that potential for tshuvah is manifested in the present life of the Jew, then the past is transformed, in a cyclical pattern. A mathematical model of time and change from the Theory of Topological Dynamics will be discussed. In this theory, there is (i) a time component T (topological group); (ii) a universe component U (topological space); and (iii) a mapping f:T x U  > U, in which each moment of time represents a rearrangement of the universe U. We shall examine various properties of this mathematical model and evaluate them in the context of Jewish time: (1) The structure of T implies that one can naturally move from any one point in time to any other point in time; and (2) f is continuous, which implies that change is gradual.
