Ghost busting: PT -symmetric interpretation of the Lee model
1550-7998=20 The Lee model was introduced in the 1950s as an elementary quantum field theory in which mass, wave function, and charge renormalization could be carried out exactly. In early studies of this model it was found that there is a critical value of g2, the square of the renormalized coupling constant, above which g0, the square of the unrenormalized coupling constant, is negative. Thus...

In early studies of this model it was found that there is a critical value of g2, the square of the renormalized coupling constant, above which g2 0 , the square of the unrenormalized coupling constant, is negative. Thus, for g2 l...

mortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
