On analytic semigroups and cosine functions in Banach spaces [PDF]

, 1998
If A generates a bounded cosine function on a Banach space X then the negative square root B of A generates a holomorphic semigroup, and this semigroup is the conjugate potential transform of the cosine function. This connection is studied in detail, and

Inequalities for analytic functions associated with hyperbolic cosine function

Қарағанды университетінің хабаршысы. Математика сериясы
In this paper, we investigate the geometric properties of a specific subclass of analytic functions satisfying  the condition f' (z) ≺ cosh(√ z) meaning that the function f '(z) is subordinate to the function cosh(√ z).

Time-domain finite element method based on smoothed cosine temporal basis function for three-dimensional EM radiation problem

, 2008
A novel time-domain finite element method (TDFEM) based on Smoothed Cosine temporal basis function is presented in this paper. This method is motivated by goals of achieving higher computational efficiency.

Pricing Early-Exercise and Discrete Barrier Options by Fourier-Cosine Series Expansions

We present a pricing method based on Fourier-cosine expansions for early-exercise and discretely-monitored barrier options. The method works well for exponential Levy asset price models. The error convergence is exponential for processes characterized by
