We form ulate the necessary and sufficient conditions for the existence of an open -loop Nash equilibrium in this class of differential games.  We specialize these results to linear-quadratic games\, and show that the open-loop Nas h equilibrium strategies can be computed by solving a constrained non-line ar optimization problem. For a specialized canonical linear-state differen tial game\, we obtain analytical solutions for equilibrium number\, timing and level of impulses. In particular\, we show that there can be at most one interior impulse in the open-loop Nash equilibrium and the level of im pulse depends only on the problem parameters. When the timing of impulse i s exogenously given\, we recover the classical result that the open-loop N ash equilibrium and feedback Nash equilibrium coincide for deterministic l inear-state differential games. When Player 2 decides the number and timin g of impulses besides the size of impulses\, we find the classical result does not hold\, that is\, open-loop and feedback Nash equilibrium are diff erent.\n \n This is a joint work with Puduru Viswanadha Reddy and Georges Za ccour.\n \n Bio: ‪\n\nUtsav Sadana‬ is a final year PhD student in the Depar tment of Decision Sciences at HEC Montreal\, working under the supervision of Professor Georges Zaccour.
