On the epistemic account of vagueness put forward by Williamson, the intransitivity of the relation of indiscriminability is presented as the main source for vagueness ([5]: 237). In [4] and in t...

Magnetohydrodynamics (MHD) stagnation point flow and heat transfer of a Williamson fluid in the direction of an exponentially stretching sheet embedded in a thermally stratified medium subject to suction present in this examination. Suitable transformations are used to convert the partial differential equations corresponding to the momentum and energy equations into highly nonlinear ordinary di...
