Necessary Conditions without Differentiability Assumptions in Unilateral Control Problems*
We derive two theorems combining existence with necessary conditions for the relaxed unilateral problem of the optimal control of ordinary differential equations in which the functions that define the problem are Lipschitz-continuous in the state variables. These theorems generalize the results presented in a previous paper [8] by the addition of unilateral constraints on the state and control ...
متن کاملOn the Necessary and Sufficient Assumptions for UC Computation
We study the necessary and sufficient assumptions for universally composable (UC) computation, both in terms of setup and computational assumptions. We look at the common reference string model, the uniform random string model and the key-registration authority model (KRA), and provide new results for all of them. Perhaps most interestingly we show that: – For even the minimal meaningful KRA, w...

متن کاملNecessary and Sufficient Assumptions for Non-iterative Zero-Knowledge Proofs of Knowledge for All NP Relations
Establishing relationships between primitives has been an important area in the foundations of Cryptography, since the first days of modern Cryptography. In some cases, researchers have been successful in presenting necessary and sufficient conditions for the existence of primitives. For instance, it is known that the existence of one-way functions is necessary and sufficient for the constructi...
متن کاملSensitivity analysis: distributional assumptions and confounding assumptions.
In a presentation of various methods for assessing the sensitivity of regression results to unmeasured confounding, Lin, Psaty, and Kronmal (1998, Biometrics54, 948-963) use a conditional independence assumption to derive algebraic relationships between the true exposure effect and the apparent exposure effect in a reduced model that does not control for the unmeasured confounding variable. How...
