In hot pursuit of a stable wormhole in beyond Horndeski theory
S. Mironov, V. Rubakov, V. Volkova
We consider the issue of stability at the linearized level for static, spherically symmetric wormhole solutions within a subclass of scalar-tensor theories of beyond Horndeski type…

Stable non-singular cosmologies in beyond Horndeski theory and disformal transformations
S. Mironov, V. Volkova
In this note we collect, systemise and generalise the existing results for relations between general Horndeski theories and beyond Horndeski theories via disformal transformations…
