AB We analyze the emergence of classical inflationary universes in a kinetic-dominated stage using asuitable class of solutions of the Wheeler-DeWitt equation with a constant potential. These solutions areeigenfunctions of the inflaton momentum operator that are strongly peaked on classical solutionsexhibiting either or both a kinetic-dominated period and an inflation period. Our analysis is based onsemiclassical WKB solutions of the Wheeler-DeWitt equation interpreted in the sense of Borel (toperform a correct connection between classically allowed regions) and on the relationship of thesesolutions to the solutions of the classical model. For large values of the scale factor the WKB Vilenkintunneling wave function and the Hartle-Hawking no-boundary wave functions are recovered as particular instances of our class of wave functions.
