A tropical motivic Fubini theorem with applications to Donaldson–Thomas theory [PDF]

Duke mathematical journal, 2017
We present a new tool for the calculation of Denef and Loeser's motivic nearby fiber and motivic Milnor fiber: a motivic Fubini theorem for the tropicalization map, based on Hrushovski and Kazhdan's theory of motivic volumes of semi-algebraic sets.

Eilenberg-Watts calculus for finite categories and a bimodule Radford 𝑆⁴ theorem [PDF]

Transactions of the American Mathematical Society, 2016
We obtain Morita invariant versions of Eilenberg-Watts type theorems, relating Deligne products of finite linear categories to categories of left exact as well as of right exact functors.

Soft theorems in de Sitter spacetime

Journal of High Energy Physics
In this paper, we derive a soft photon theorem and a soft gluon theorem in the de Sitter spacetime from the Ward identity of the near cosmological horizon large gauge transformation.

The convolution algebra H1(R)

Journal of Function Spaces and Applications, 2010
H1(R) is a Banach algebra which has better mapping properties under singular integrals than L1(R) . We show that its approximate identity sequences are unbounded by constructing one unbounded approximate identity sequence {vn}.

A generalized nonlinear Picone identity for the p-biharmonic operator and its applications

Journal of Inequalities and Applications, 2019
A generalized nonlinear Picone identity for the p-biharmonic operator is established in this paper. As applications, a Sturmian comparison principle to the p-biharmonic equation with singular term, a Liouville’s theorem to the p-biharmonic system, and a ...

Notes on the Hypercyclic Operator

Journal of Mathematical Extension, 2008
In this paper by using a nice criterion, we show that the perturbation of identity operators by some multiples of the standard backward shift is hypercyclic. This gives a new proof for Salas Theorem in ( [10 ], Theorem 3.3).

Structure of Finite-Dimensional Protori

Axioms, 2019
A Structure Theorem for Protori is derived for the category of finite-dimensional protori (compact connected abelian groups), which details the interplay between the properties of density, discreteness, torsion, and divisibility within a finite ...

The hybrid mean value of Dedekind sums and two-term exponential sums

Open Mathematics, 2016
In this paper, we use the mean value theorem of Dirichlet L-functions, the properties of Gauss sums and Dedekind sums to study the hybrid mean value problem involving Dedekind sums and the two-term exponential sums, and give an interesting identity and ...
