We study inhomogeneous multidimensional cosmological models with a higher dimensional space-time manifold M = M0 × ∏n i=1 Mi (n ≥ 1) under dimensional reduction to D0-dimensional effective models and show that small inhomogeneous excitations of the scale factors of the internal spaces near minima of effective potentials should be observable as massive scalar particles (gravitational excitons) i...

We introduce the following general question: Let V be a complex n-dimensional space and for m k consider the GL V -module V n m k V m defined by V n m k f v vm V m dimSpanfv vmg k g We would like to determine dimV n m k for any choice of n m k. This question appears in various disguises in computer vision problems where the constraints of a multi-linear problem occupy a lowdimensional subspace....

This paper advocates an epistemological turn in the field of digital art history and cultural heritage studies. is understood as elaboration a new (or renewed) epistemic apparatus that allows us to understand interpret phenomena from perspective different order thought. labor conceived «epistemological technical practice», which means integrating reflection production into making design. Within...

A normed space $mathfrak{X}$ is said to have the fixed point property, if for each nonexpansive mapping $T : E longrightarrow E $ on a nonempty bounded closed convex subset $ E $ of $ mathfrak{X} $ has a fixed point. In this paper, we first show that if $ X $ is a locally compact Hausdorff space then the following are equivalent: (i) $X$ is infinite set, (ii) $C_0(X)$ is infinite dimensional, (...
