TL;DR

This paper constructs a four-dimensional multisupergravity model from a discretized five-dimensional supergravity and evaluates its one-loop vacuum energy, suggesting a link between discretized M-theory and string theory.

Contribution

It introduces a novel approach to derive multisupergravity from latticized extra dimensions and explores potential connections to M-theory and string theory.

Findings

One-loop vacuum energy computed for different boundary conditions.

Framework for relating discretized M-theory to string theory.

Potential implications for higher-dimensional supergravity models.

Abstract

The construction of the linearized four-dimensional multisupergravity from five-dimensional linearized supergravity with discretized fifth dimension is presented. The one-loop vacuum energy is evaluated when (anti)periodic boundary conditions are chosen for (bosons) fermions, respectively or vice-versa. It is proposed that the relation between discretized M-theory and strings may be found in the same fashion.
