An Overview of the Pathway Idea and Its Applications in Statistical and Physical Sciences

Axioms, 2015
Pathway idea is a switching mechanism by which one can go from one functional form to another, and to yet another. It is shown that through a parameter α, called the pathway parameter, one can connect generalized type-1 beta family of densities ...

Derived Hyperstructures from Hyperconics

Mathematics, 2020
In this paper, we introduce generalized quadratic forms and hyperconics over quotient hyperfields as a generalization of the notion of conics on fields.

Supertropical Quadratic Forms I [PDF]

, 2015
We initiate the theory of a quadratic form $q$ over a semiring $R$. As customary, one can write $$q(x+y) = q(x) + q(y)+ b(x,y),$$ where $b$ is a companion bilinear form.

When Flexible Forms Are Asked to Flex Too Much

Journal of Agricultural and Resource Economics, 1994
Taylor series-based flexible forms cannot be interpreted as Taylor series approximations unless all data used in estimation lie in a region of convergence.

A Quantitative Oppenheim Theorem for generic ternary quadratic forms [PDF]

, 2016
We prove a quantitative version of Oppenheim's conjecture for generic ternary indefinite quadratic forms. Our results are inspired by and analogous to recent results for diagonal quadratic forms due to Bourgain.

A note on concentration for polynomials in the Ising model [PDF]

, 2018
We present precise multilevel exponential concentration inequalities for polynomials in Ising models satisfying the Dobrushin condition. The estimates have the same form as two-sided tail estimates for polynomials in Gaussian variables due to Lata{\l}a ...

Inductive graded rings, hyperfields and quadratic forms [PDF]

Categories and General Algebraic Structures with Applications
In [6] we developed a k-theory for the category of hyperbolic hyperfields (a category that contains a copy of the category of (pre)special groups): this construction extends, simultaneously, Milnor's k-theory ([20]) and Dickmann-Miraglia's k-theory ([13])

Essential dimension, spinor groups and quadratic forms [PDF]

, 2009
We prove that the essential dimension of the spinor group Spin_n grows exponentially with n; in particular, we give a precise formula for this essential dimension when n is not divisible by 4.
