چکیده
3. It is claimed that x + y + z = n has a solution x, y, z in Z for all n not of the form 9k± 4 (it has been proved that every number not of that form can be written as a sum of four integer cubes). This has been verified for all n ≤ 1000 except for n = 33, 42, 74, 114, 156, 165, 318, 366, 390, 420, 564, 579, 627, 633, 732, 758, 789, 795, 894, 906, 921, 933, 948, 975. Find solutions for any of these.

Statement Chris Peikert December 22 , 2008 1 New Foundations for Cryptography
Most cryptographic tasks must inherently rely on assumptions about the difficulty of some computational problem. Over the past three decades, number theory has served as the primary source of seemingly hard problems for cryptography; for instance, a prototypical conjecture is that it is infeasible to factor the product of two large, random prime numbers. Many such number-theoretic problems have...

متن کاملContext-Dependent Effects of Goal Primes
We provide evidence that goal priming effects are context dependent. We show that goal primes encourage prime-consistent behavior when the behavioral context is common and prime-inconsistent behavior when the behavioral context is uncommon. While the prime-consistent behavior is compatible with existing theory, the prime-inconsistent behavior poses a theoretical challenge. We argue that uncommo...
متن کاملExistence of positive solutions for fourth-order boundary value problems with three- point boundary conditions
In this work, by employing the Krasnosel'skii fixed point theorem, we study the existence of positive solutions of a three-point boundary value problem for the following fourth-order differential equation begin{eqnarray*} left { begin{array}{ll} u^{(4)}(t) -f(t,u(t),u^{prime prime }(t))=0 hspace{1cm} 0 leq t leq 1, & u(0) = u(1)=0, hspace{1cm} alpha u^{prime prime }(0) - beta u^{prime prime pri...
