Published in 2019 at "Journal of High Energy Physics"

DOI: 10.1007/jhep02(2019)191

Abstract: A bstractQCD in non-integer d = 4 − 2ϵ space-time dimensions enjoys conformal invariance at the special fine-tuned value of the coupling. Counterterms for composite operators in minimal subtraction schemes do not depend on ϵ… read more here.

Published in 2019 at "Semigroup Forum"

DOI: 10.1007/s00233-019-10045-w

Abstract: In this work, we study the existence and uniqueness of almost automorphic solutions for semilinear nonautonomous parabolic evolution equations with inhomogeneous boundary conditions using the exponential dichotomy. We assume that the homogeneous problem satisfies the… read more here.
