Constructing more non-singular Sp-branes

TL;DR

This paper constructs a variety of non-singular Sp-brane solutions in arbitrary dimensions, featuring time-dependent profiles of dilaton and form fields, by analytically continuing non-extremal dihole solutions.

Contribution

It introduces a new method to generate non-singular, time-dependent Sp-brane solutions from black p-branes via analytic continuation.

Findings

Successfully constructed non-singular Sp-branes in various dimensions.

Demonstrated time-dependent profiles of dilaton and form fields.

Extended solutions to include non-extremal dihole configurations.

Abstract

In this note, we construct an array of non-singular Sp (where p=D-4) branes in arbitrary $D$ dimensions starting from static solutions of black $p$ brane. These solutions carry nontrivial time dependent profiles of dilaton and associated form fields. We also study other non-singular time dependent configurations. These are obtained from proper analytic continuations of non-extremal diholes.
