We present in this paper the evaluation of multiloop Green's functions in the context of a
recently proposed regulating scheme called operator regularization. We show that, in contrast …

Operator regularization is used to compute the renormalization group functions β(λ), γ m (λ),
and γ Γ (λ) to two-loop order in φ 6 3 theory. At no stage in the computation do we encounter …

Chicago Board of Options Exchange (CBOE) transactions call data for 1987 to 1989 show
that the constant-variance model of Black and Scholes (and its dividend variant by Roll) has …

The expansion of the functional matrix element< x‖ exp {-[(p+ A) 2+ f] t}‖ y> in powers of t
for x≠ y is considered. The well-known limiting case in which x= y is recovered. Several …

We examine delta-neutral call spreading strategies on the Chicago Board Options Exchange
between January 1987 and December 1989 and find substantial profits net of transaction …

This paper finds significant mispricing between puts differing only in their exercise price or
maturity on the Chicago Board Options Exchange (CBOE) for 1987, 1988 and 1989. Using a …

In the past few years a new method of regularization, called operator regularization (or), has
been developed to regulate formal divergences that arise in quantum field theory. This …

The use of laparoscopic gastric banding is a consolidated surgical procedure in bariatric
surgery for patients with morbid obesity. Major complications with this technique are uncommon …
