الوصف: | Classically, solution theories for state-dependent delay equations are developed in spaces of continuous or continuously differentiable functions. In applications, these two approaches naturally offer some limitations. The former can be technically challenging to apply in as much as suitably Lipschitz continuous extensions of mappings onto (open subsets of) the space of continuous functions are required; whereas the latter approach leads to potentially undue restrictions on the class of initial pre-histories. Here, we establish a solution theory (i.e., unique existence) for state-dependent delay equations for arbitrary Lipschitz continuous pre-histories and suitably Lipschitz continuous right-hand sides on the Sobolev space $H^1$. The provided solution theory is independent of previous ones and is based on the contraction mapping principle on exponentially weighted spaces yielding global in time well-posedness right away. In particular, initial pre-histories are not required to belong to certain solution manifolds and the generality of the approach permits the consideration of a large class of functional differential equations even when the continuity of the right-hand side has constraints on the derivative. The solution theory provided implies the classical Picard--Lindel\"of theorem as a special case. Comment: 27 pages; references added, typos removed |
