Geometric Local Variance Gamma Model [PDF]

open access: yesThe Journal of Derivatives, 2019
This paper describes another extension of the Local Variance Gamma model originally proposed by P. Carr in 2008, and then further elaborated on by Carr and Nadtochiy, 2017 (CN2017), and Carr and Itkin, 2018 (CI2018). As compared with the latest version of the model developed in CI2018 and called the ELVG (the Expanded Local Variance Gamma model), here ...

PRICING EUROPEAN OPTIONS IN THE VARIANCE GAMMA MODEL

open access: yesQuantitative Methods in Economics, 2019
The purpose of the article was to investigate if it is posssible to speed up the process of pricing European options in the variance gamma setting. The analysis carried out for this purpose refers to the choice of the Fourier transform scheme, which allows to obtain accurately and fast the final result (theoretical value of the European option).

Extension of Short Rate Model Under a Lévy Process

open access: yesFountain Journal of Natural and Applied Sciences (FUJNAS), 2023
A lot of abnormalities occur in real-life scenarios, thus leading to some difficulties in modelling such scenarios without a deeper understanding of certain aspects of Lévy processes.

Special greeks of a variance-gamma driven vasicek model

open access: yesScientific African, 2023
Abrupt happenings in financial markets have resulted to the need to adopt Lévy processes such as a variance gamma process in modelling financial derivatives since it has the ability to capture jumps that occur in such scenario.

Sand-Dust Image Enhancement Using Chromatic Variance Consistency and Gamma Correction-Based Dehazing

open access: yesSensors, 2022
In sand-dust environments, the low quality of images captured outdoors adversely affects many remote-based image processing and computer vision systems, because of severe color casts, low contrast, and poor visibility of sand-dust images.
