THE COMPLEX INVERSION FORMULA REVISITED

The Schwinger formula revisited

Departament de Matemàtica Aplicada I, Universitat Politècnica de Catalunya, Diagonal 647, 08028 Barcelona, Spain. e-mail: [email protected] Abstract We apply the formal W.K.B. method in the complex plane to the quantum field theory to obtain the Schwinger formula for spin and spinless particles; i.e., we obtain the probability that the vacuum state remains unchanged in presence of a constant el...

The Adrogue-Madias formula revisited.

F ew subjects engender as much heated discussion at various nephrology meetings as the strongly held views by advocates of various approaches to the management of hyponatremia (1). The controversy as to how these patients should best be treated can be traced to the fact that even in a specialty such as ours, which already suffers from a dearth of properly conducted prospective, randomized, cont...

Zeno product formula revisited

We introduce a new product formula which combines an orthogonal projection with a complex function of a non-negative operator. Under certain assumptions on the complex function the strong convergence of the product formula is shown. Under more restrictive assumptions even operator-norm convergence is verified. The mentioned formula can be used to describe Zeno dynamics in the situation when the...

Ball’s Formula Method Revisited

This manuscript describes a review and analysis of the correction factor for come-up time (CUT), introduced by Dr. C. Olin Ball in his famous Formula Method for thermal process calculations. This correction factor has commonly been considered applicable only to the Ball Formula method. In the alternative General Method, the effect of CUT is automatically included in the calculated lethality val...
