Title: Codimensions of polynomial identities of representations of Lie algebras

Abstract: S.A. Amitsur's conjecture about the asymptotic behaviour of codimensions of polynomial identities was proved by A. Giambruno and M.V. Zaicev for all associative and finite dimensional Lie algebras. We prove its analogue for polynomial identities of finite dimensional representations of Lie algebras.

Title: Effective cloaking of an object through spacetime curvature

Abstract: Motivated by recent advancements in the design of optical cloaks, we ask the question: is it possible to use the curvature of spacetime to cloak an object? The answer: kind of. We present a spherically symmetric geometry which allows an object of arbitrary size (when placed at the geometric center) to appear arbitrarily small from the outside. The metric of the "effective cloaking" spacetime is presented, and it's properties are explored.
