The phrase "essential hypothesis" is correct and can be used in written English
You can use it when you are highlighting a particular hypothesis that is necessary in order to reach a particular conclusion. For example: "We tested the essential hypothesis that the vaccine would reduce the symptoms of the virus, and our results proved its efficacy."
Section 2 presents the essential hypothesis of the bispectrum, picture preparing, and fractal measurement.
Remark 2.1 The symmetry character of the above involved mean is, by definition, taken as essential hypothesis.
Low blood GLN levels have been observed in this patient population [ 28, 29], and the conditionally essential hypothesis may apply to them.
The essential hypotheses at the bases of the duration model are: (i) it exists a TTB; (ii) the individual decision to continue the mobility for a time ΔT, after a TTE T, is the realisation of an independent random event whose probability decrease proportionally to ΔT.
The essential hypotheses that the two arguments hold are below: (Lin 1993) As long as j-type members exist, the free right to exit is a necessary condition for high-effort equilibrium, i.e. in the absence of free exit rights, the high-effort equilibrium cannot be sustained.
This seems to contradict the essential tRNA hypothesis as well as our hypothesis, which can be termed the "essential plastid translation hypothesis".
This conjecture implies the essential simplicity hypothesis that almost all zeros of the zeta-function are simple.
Comparative genomics based on sequenced referenced genomes is essential to hypothesis generation and testing within population genetics.
Confirmation of model predictions by subsequent experimentation is essential for hypothesis testing and model validation (Kohn 1995).
The most plausible is the essential tRNA hypothesis, which postulates that trnE-UUC is the main reason for plastome conservation since it is essential for heme biosynthesis.
We conclude that underwater investigation is essential if hypotheses of early human adaptation and dispersal are to be fully tested.
