On the role of the parity violating Hojman–Holst term in gravity theories
Physics Letters BWe study Parity Violating Gravity Theories whose gravitational Lagrangian is a generic function of the scalar curvature and the parity odd curvature pseudoscalar, commonly known as the Holst (or Hojmann) term.

S- and T-self-dualities in dilatonic $$f(R)$$ f ( R ) theories
European Physical Journal C: Particles and Fields, 2017 We search for theories, in general spacetime dimensions, that would incorporate a dilaton and higher powers of the scalar Ricci curvature such that they have exact S- or T-self-dualities. The theories we find are free of Ostrogradsky instabilities.

Effective Gravitational “Constant” in Scalar-(Curvature)Tensor and Scalar-Torsion Gravities
Universe, 2017 In theories where a scalar field couples nonminimally to gravity, the effective gravitational “constant” becomes dependent on the value of the scalar field.

Colliding scalar pulses in the Einstein-Gauss-Bonnet gravity
EPJ Web of Conferences, 2018 We numerically investigated how the nonlinear dynamics depends on the dimensionality and on the higher-order curvature corrections in the form of Gauss-Bonnet (GB) terms, with a model of colliding scalar pulses in plane-symmetric space-time.

Multiply Warped Products with a Semisymmetric Metric Connection
Abstract and Applied Analysis, 2014 We study the Einstein multiply warped products with a semisymmetric metric connection and the multiply warped products with a semisymmetric metric connection with constant scalar curvature, and we apply our results to generalized Robertson-Walker space ...
