If my understanding is correct, an aircraft stalls beyond that AOA
which, when increased any further, produces no (further) lift. If
correct, would it be logical to infer that an aircraft's stalling AOA:

a. is dependent on its airspeed, and is independent of its weight and
weight distribution, and

No, the stall AOA is independent of both airspeed and weight.


b. varies, for a given airspeed, with the air density (altitude)


No the stall AOA does not vary with density.


The stall AOA is determined by the shape of the wing. It is independent of
weight and airspeed. However, the airspeed vs AOA relationship depends on a
variety of factors, such as weight and density. This is why stall speed is
somewhat a misleading quantity. AOA would be a better quantity.
Unfortunately there is no direct way to measure the AOA in most aircraft,
so we use the airspeed as an indirect indication of the AOA.
