General Properties of Multiscalar RG Flows in $d=4-\varepsilon$
Fixed points of scalar field theories with quartic interactions in$d=4-\varepsilon$ dimensions are considered in full generality. For suchtheories it is known that there exists a scalar function $A$ of the couplingsthrough which the leading-order beta-function can be expressed as a gradient.It is he...
