Covariant derivative expansion of Yang-Mills effective action at high temperatures [PDF]

, 2003
Integrating out fast varying quantum fluctuations about Yang--Mills fields A_i and A_4, we arrive at the effective action for those fields at high temperatures.

Slowly varying functions in the complex plane [PDF]

Transactions of the American Mathematical Society, 1976
Let f be analytic and have no zeros in | arg ⁡ z | > α ⩽ π |\arg z| > \alpha \leqslant \pi ; f is called slowly varying if, for every λ > 0 , f ( λ z ) /

Cosmological models from quintessence [PDF]

, 2000
A generalized quintessence model is presented which corresponds to a richer vacuum structure that, besides a time-dependent, slowly varying scalar field, contains a varying cosmological term.

Slowly varying functions and asymptotic relations

Journal of Mathematical Analysis and Applications, 1971
Abstract : A survey of basic properties of slowly varying functions is given. The notion of quasi monotone functions is introduced and it is shown that a quasi monotone slowly varying function can be represented as a quotient of two non decreasing functions.

New results on slowly varying functions in the Zygmund sense [PDF]

Proceedings of the Japan Academy, Series A, Mathematical Sciences, 2020
A positive and measurable \(g\) is self-neglecting (notation: \(g \in SN\)) if it satisfies \[ \frac{g(x+yg(x))}{g(x)} \to 1, \forall y \in \mathbb{R} \] and locally uniformly in \(y\). A positive and measurable function \(a\) is in the class \(\Gamma _{\alpha} (g)\) if \(g \in SN\) and if \[ \frac{a(x+yg(x))}{a(x)} \to e ^{\alpha y}, \forall y \in ...

Slowly modulated oscillations in nonlinear diffusion processes [PDF]

, 1977
It is shown here that certain systems of nonlinear (parabolic) reaction-diffusion equations have solutions which are approximated by oscillatory functions in the form R(ξ - cτ)P(t^*) where P(t^*) represents a sinusoidal oscillation on a fast time scale t*
