A classical case was reported by Wigan [ 32], who described the first non-fictional account of a man who could induce a visual hallucination of himself.
The structure of the maximal ideal space is also investigated; in particular, an open dense subset, just like the open unit disc in the classical case, is determined.
The classical case is the case of Jensen-convex (or mid-convex) functions.
In the same way, free cumulants can also be described combinatorially, the only difference to the classical case is the replacement of partitions by the so called non-crossing partitions [39].
Remark 2.8 For q → 1, equation (2.4) takes the form u ( t ) = ∫ 0 t ( t − q s ) y ( s ) d q s + a 1 t + a 0, which is the solution of a classical second-order ordinary differential equation u ″ ( t ) = y ( t ) and the associated form of Green's function for the classical case is G ( t, s ) = 1 α { 1 − α + α t, s ≤ t, 1 − α + α s, t ≤ s.
One classical case was that of a woman who was brought to the Primary Health Care (PHC) facility at the third stage of labour after being mismanaged by a community-based Traditional Birth Attendant.
The parameter is some real number modulo 2, the classical case being obtained when it is an integer.
One of the most classical cases is the application of (21) to finite-dimensional SDEs d u t = g ( u t ) d t + ϵ G ( u t ) d β t (22).
Clinically classifying TTN cases into classical (n = 19) and severe (n = 6) forms, classical cases were reported to have only a mild LV dysfunction on the first day, whereas severe cases had significant LV and RV dysfunctions [ 7].
