Simultaneous preconditioning and symmetrization of non-symmetric linear systems
Motivated by the theory of self-duality which provides a variational formulation and resolution for non self-adjoint partial differential equations [6, 7], we propose new templates for solving large non-symmetric linear systems. The method consists of combining a new scheme that simultaneously preconditions and symmetrizes the problem, with various well known iterative methods for solving linea...
متن کاملSymmetrization, convexity and applications
Based on permutation enumeration of the symmetric group and ‘generalized’ barycentric coordinates on arbitrary convex polytope, we develop a technique to obtain symmetrization procedures for functions that provide a unified framework to derive new Hermite-Hadamard type inequalities. We also present applications of our results to the Wright-convex functions with special emphasis on their key rol...

متن کاملSymmetrization and Rademacher Complexity
Let’s first see how primitive covers were inadequate. Recall that a function class G is a primitive cover for a function class F at scale > 0 over some set S if: • G ⊆ F , • |G| <∞, and • for every f ∈ F there exists g ∈ G with supx∈S |g(x)− f(x)| ≤ . Last class, we gave a generalization bound for classes with primitive covers (basically, primitive covers give discretizations, and then we apply...
متن کاملSymmetrizing The Symmetrization Postulate
Reasonable requirements of (a) physical invariance under particle permutation and (b) physical completeness of state descriptions [1], enable us to deduce a Symmetric Permutation Rule(SPR): that by taking care with our state descriptions, it is always possible to construct state vectors (or wave functions) that are purely symmetric under pure permutation for all particles, regardless of type di...
