The question: Where does projective geometry fit in generalized geometries like KCC-theory, Lagrange geometry, or Finsler geometry?..is discussed.

Explains why Stratonovich stochastic calculus is the natural one to use for the study of processes on smooth manifolds

KCC-theory of SODE's on manifolds, sprays (SODE's), equations of geodesics in Finsler 2-manifolds, the Finsler metric functional, Euler-Lagrange equations, regular metric tensors, Berwald's frame, angular metric tensor, horizontal and vertical Christoffel symbols and Cartan's torsion tensor, principal scalar, I, projective geometry, Rashevsky's inv...

In order to understand them it will suffice to think about the Berwald Basis { δ i , ´ ∂ i }. If X is a vector field on TM, then one decomposes to obtain "uniquely"(see below) X = X m δ m + ´ X m ´ ∂ m with X m being the HORIZONTAL COMPONENT and the other (with dot) is the VERTICLE COMPONENT. One can formalize this: TTM = HTM ⊕ VTM. A purely vertic...

After brief summaries of several models of evolution of coral/algal symbiosis, stochastic Nelson mechanics is used to prove long-term heat stress can actually benefit scleractinian corals and their symbionts.

A model of L. Margulis' serial endosymbiosis theory, using projective geometry, is shown to be compatible with G.S. Ferreira Jr's recent model of tissue formation, which is based on differential adhesion of cells and Finslerian anholonomic frames describing phenotypic deformation. The Gould-Eldredge theory of punctuated equilibria is herein modelle...

We extend the Eco-strain Model of a Forest, presented previously and based on analogy with continuous media physics, to include the understory Plant Community and the underground Mycorrhizal Network (PC-MN). Using this, we provide a model of carbon cycling, in particular, and nutrient cycling, in general.

A model of tissue formation is presented, extending M. Steinberg's thermodynamic Differential Adhesion Mechanism to include cell membrane structures.

This PDF replaces the just removed Power Point version of my Independence day talk at UFPE. It is exactly the same.

These are notes(40 pp) of a short course I gave in the Summer,2012, at Dmat, UFPE, Recife. They were translated into Portuguese by Dr. Claudio Cristino. My original notes were hand written in English. There are some type-o's caught recently and corrections are indicated in the file.

The role of curvature in Riemannian and Finslerian Markov Diffusions is discussed. Applications in ecology, evolution, epidemiology, genetics and developmental biology are presented, briefly. Refereneces to published papers in the various applications are listed and/or are downloadable.

Some elementary remarks on tensors, covariance and non-integrable deformations, pertinent to the Finsler Gate Theorem

Paper gives a lucid account of the Kron-Kondo method of anholonomy. Furthermore, The Kondo paper can be read at the website of Japan J. Aerodynamical engineering, vol.2,#7, 1954..some Japanese characters are displayed so you can’t read it after you download it, without special reader. Also see the 2nd part in same J but 1953, vol.2 The Kondo part 1...

Further remarks on Non-Riemannian geometries and applications..especially the significance of projective geometry in Finsler's theory, the Darboux- Matsumoto theorem and consequences. Namely, every quadratic 2-spray is projectively Berwald, i.e.,to one of the 3 Berwald classes for dimension 2. If the quadratic spray is not projectively flat, then i...

Comments about Elsevier 's publishing policies. Moreover, the same thing(fired most editors , hired a new set) happened recently with theJournal of Experimental Marine Biology and Ecology..an Elsevier journal..just more evidence of corporate takeover of academia!!

Two remarks on our paper.. Gradient Driven Dynamics on Finsler Manifolds: The Jacobi Action-Metric Theorem and an Application in Ecology

A dynamical model of the environmental impact of transgenic crop on normal varieties in the presence of environmental noise is presented. Previous results used only the deterministic equations to cover external perturbations. Analytical Trophodynamics with spatial diffusion dispersion mechanisms is now augmented with Finslerian noise. We conclued t...

This work can be considered a prequel to our previous paper on coral bleaching induced by global warming. We once again investigate, using Finsler geometry, dynamical energy budget theory and nonlinear modular mechanics, the origin of endosymbiosis, between reef-building corals and the algae. We assume their relationship starts out as entosymbiosis...

Junior on the analysis of competition between a transgenic crop and its natural variant with the addition of noisy , modeling an uncertain environment . A modified form this paper will appear in the journal, Nonlinear Studies, in the near future.

An over view with historical perspective on allometry ideas is presented. The search for the Holy Grail, or bauplan for ontogenesis goes beyond straight line regressions to try to find cellular dynamical equations relevant to developmental biology and which satisfy the Huxley/Needham allometric law.

Following the Antonelli/Rutz Finsler Gate method, the concept of Allometric Strain is introduced to model plastic deformation of phenotypes in mammalian genomes. Focus is on a model of muscle and adipose (fat) cell populations, which produce hormones adiponectin and IL- 6, which mediate their interactions. The model shows that genetic switching is...
