Say that a model's interpration assigns true to A and false to B. Then the valuation function assigns false to not A , true to not B , false to A implies B , false to A and B , and true to A or B .
The distinction here made between climatic and physiographic climaces is admittedly somewhat arbitrary, but the underlying idea is one of great practical as well as theoretical importance.[…]In other words, physiographic climaces of this description represent the climatic climax.[…]The climatic climax is attained on the better sites, but on much of the area coniferous forests occur, which represent physiographic climaces due to local edaphic or topographic factors.[…]Elsewhere, owing to the effect of factors which preclude the development of the regional type, the succession of vegetation may be halted lower down in the successional series and physiographic climaces result.
