Degenerate Diffusion Operators Arising in Population Biology [PDF]

open access: green, 2011
We analyze a class of partial differential equations that arise as "backwards Kolmogorov operators" in infinite population limits of the Wright-Fisher models in population genetics and in mathematical finance. These are degenerate elliptic operators defined on manifolds with corners. The classical example is the Kimura diffusion operator, which acts on

Pragmatic turn in biology: From biological molecules to genetic content operators

open access: diamondWorld Journal of Biological Chemistry, 2014
Erwin Schrödinger's question "What is life?" received the answer for decades of "physics + chemistry". The concepts of Alain Turing and John von Neumann introduced a third term: "information". This led to the understanding of nucleic acid sequences as a natural code. Manfred Eigen adapted the concept of Hammings "sequence space".

On the approximation theorem of Wong-Zakai type for the Lasota operator [PDF]

open access: yesOpuscula Mathematica, 2010
We consider in this paper a stochastic evolution equation with Professor A. Lasota's operator as the infinitesimal generator of a strongly continuous semigroup of transformations and with Hammerstein operator connected with a noise being the Wiener ...

A study of incomplete I-functions relating to certain fractional integral operators

open access: yesApplied Mathematics in Science and Engineering, 2023
The study discussed in this article is driven by the realization that many physical processes may be understood by using applications of fractional operators and special functions. In this study, we present and examine a fractional integral operator with

Applications of the Neutrosophic Poisson Distribution for Bi-Univalent Functions Involving the Modified Caputo’s Derivative Operator

open access: yesFractal and Fractional, 2022
This paper establishes the upper bounds for the second and third coefficients of holomorphic and bi-univalent functions in a family which involves Bazilevic functions and μ-pseudo-starlike functions under a new operator, joining the neutrosophic Poisson ...

On the Numerical Solution of Fractional Boundary Value Problems by a Spline Quasi-Interpolant Operator

open access: yesAxioms, 2020
Boundary value problems having fractional derivative in space are used in several fields, like biology, mechanical engineering, control theory, just to cite a few.

The Fourier-Laplace Transform—A Conjugate Link Between the Material Brain and the Conscious Mind

open access: yesFrontiers in Human Neuroscience, 2021
Recent attempts to establish the quantum boundaries of life is pursued. A pre-existing view of quantum biology is supplemented by the formulation of modern advances in theoretical chemical physics and quantum chemistry.

Is defining life pointless? Operational definitions at the frontiers of biology [PDF]

open access: yesSynthese, 2017
Despite numerous and increasing attempts to define what life is, there is no consensus on necessary and sufficient conditions for life. Accordingly, some scholars have questioned the value of definitions of life and encouraged scientists and philosophers alike to discard the project.
