Zeros of Dirichlet Polynomials via a Density Criterion
Willian D. Oliveira
We obtain a necessary and sufficient condition in order that a semi-plane of the form , , is free of zeros of a given Dirichlet polynomial. The result ma…
An extremal problem related to generalizations of the Nyman-Beurling and Báez-Duarte criteria
Dimitar K. Dimitrov, Willian D. Oliveira
We establish generalizations of the Nyman-Beurling and Báez-Duarte criteria concerning lack of zeros of Dirichlet -functions in the semi-plane for . We…
Sign regularity of Maclaurin coefficients of functions in the Laguerre-Pólya class
Dimitar K. Dimitrov, Willian D. Oliveira
We prove that the signs of the Maclaurin coefficients of a wide class of entire functions that belong to the Laguerre-Pólya class posses a regular behaviour.
Techniques for effective and efficient fire detection from social media images
Marcos Bedo, Gustavo Blanco, Willian Oliveira +5
Social media could provide valuable information to support decision making in crisis management, such as in accidents, explosions and fires. However, much of the data from social m…
