A System Reanalysis of the Current Greenhouse Gases Budget of Terrestrial Ecosystems in Russia

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 10, October 2025.
Abstract This study synthesizes the budgets of three greenhouse gases (GHG, namely CO2, CH4, N2O) for Russia over two decades (2000–2009 and 2010–2019) using bottom‐up and top‐down approaches, as part of the Regional Carbon Cycle Assessment and Processes, Phase 2 (RECCAP2).

Soft bounds for local triple products and the subconvexity‐QUE implication for GL2$\mathrm{GL}_2$

open access: yesMathematika, Volume 71, Issue 4, October 2025.
Abstract We give a soft proof of a uniform upper bound for the local factors in the triple product formula, sufficient for deducing effective and general forms of quantum unique ergodicity (QUE) from subconvexity.

Triple Product L Functions and Quantum Chaos on SL(2,C) [PDF]

open access: yes, 2010
We extend the results of Watson, which link quantum unique ergodicity on arithmetic hyperbolic surfaces with subconvexity for the triple product L function, to the case of arithmetic hyperbolic three manifolds.

Toroidal automorphic forms, Waldspurger periods and double Dirichlet series

open access: yes, 2011
The space of toroidal automorphic forms was introduced by Zagier in the 1970s: a GL_2-automorphic form is toroidal if it has vanishing constant Fourier coefficients along all embedded non-split tori. The interest in this space stems (amongst others) from

Decomposable forms and automorphisms

open access: yesJournal of Number Theory, 2003
Let \(\mathcal{F}_{d}\) be the set of decomposable forms of degree \(d>0\) over an algebraically closed field \(K\) with variables in a \(K\)-vector space \(V\). Then \(\text{GL}(V) \) acts on \(\mathcal{F}_{d}\) via \(\gamma \cdot f=f\circ \gamma ^{-1}\), \(\gamma \in \text{GL}(V)\), \(f\in \mathcal{F}_{d}.\) For a given \(f\), \(\Aut(f) \) is defined

The conjugacy problem for ascending HNN‐extensions of free groups

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 4, October 2025.
Abstract We give an algorithm to solve the Conjugacy Problem for ascending HNN‐extensions of free groups. To do this, we give algorithms to solve certain problems on dynamics of free group endomorphisms.

A decomposition of the Fourier-Jacobi coefficients of Klingen Eisenstein series [PDF]

open access: yes, 2017
We investigate the relation between Klingen's decomposition of the space of Siegel modular forms and Dulinski's analogous decomposition of the space of Jacobi forms.Comment: Summary of a talk at the RIMS workshop "Automorphic Forms and Related Topics",

Correlations of the squares of the Riemann zeta function on the critical line

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 3, September 2025.
Abstract We compute the average of a product of two shifted squares of the Riemann zeta function on the critical line with shifts up to size T3/2−ε$T^{3/2-\varepsilon }$. We give an explicit expression for such an average and derive an approximate spectral expansion for the error term similar to Motohashi's.

Igusa quartic and Borcherds products [PDF]

open access: yes, 2014
By applying Borcherds' theory of automorphic forms on bounded symmetric domains of type IV, we give a 5-dimensional linear system of automorphic forms of weight 6 on Igusa quartic 3-fold which induces an S_6-equivariant rational map of degree 16 from ...
