Stabilization of linear continuous time-varying systems with state delays in Hilbert spaces

Electronic Journal of Differential Equations, 2001
This paper studies the stabilization of the infinite-dimensional linear time-varying system with state delays $$dot x = A(t)x + A_1(t)x(t-h)+B(t)u,.$$ The operator $A(t)$ is assumed to be the generator of a strong evolution operator.

Fourier integrals and a new representation of Maslov's canonical operator near caustics [PDF]

, 2013
We suggest a new representation of Maslov's canonical operator in a neighborhood of the caustics using a special class of coordinate systems (\eikonal coordinates") on Lagrangian ...

SO(1, d + 1) symmetry of the exact RG equation

Journal of High Energy Physics
There is a method for constructing from first principles, a holographic bulk dual action in Euclidean AdS d+1 space for a d-dimensional Euclidean CFT on the boundary, starting from the Polchinski’s Exact Renormalization Group (ERG) equation that ...

The induced 2-tuple linguistic generalized OWA operator and its application in linguistic decision making [PDF]

We present the induced 2-tuple linguistic generalized ordered weighted averaging (2-TILGOWA) operator. This new aggregation operator extends previous approaches by using generalized means, order-inducing variables in the reordering of the arguments and ...
