In this work we evaluate analytically the ultraviolet divergences of Lorentz-violating massive
O (N) λ ϕ^ 4 λ ϕ 4 scalar field theories, which are exact in the Lorentz-violating mechanism …

In this work, we compute analytically the infrared divergences of massless O (N) self-
interacting scalar field theories with Lorentz violation, which are exact in the Lorentz …

The tunneling characteristics at the cosmological and event horizons of Reissner–Nordström–
de Sitter black hole with a global monopole are studied by using the modified Lorentz …

We perform the all-loop renormalization of the O (N) λ ϕ 4 scalar field theory with Lorentz
violation which is exact in the Lorentz-violating K μ ν coefficients. This task is fulfilled …

We present an explicit analytical computation of the quantum corrections, at next-to-leading
order, to the critical exponents. We employ for that the Unconventional minimal subtraction …

We probe the two-scale-factor universality hypothesis by evaluating, firstly explicitly and
analytically at the one-loop order, the loop quantum corrections to the amplitude ratios for O …

We probe the universality hypothesis by analytically computing the at least two-loop
corrections to the critical exponents for q-deformed O (N) self-interacting λ ϕ 4 scalar field …
