Finite Dimensional Representations of Leavitt Path Algebras
, 2017 When $\Gamma$ is a row-finite di(rected )graph we classify all finite dimensional modules of the Leavitt path algebra $L(\Gamma)$ via an explicit Morita equivalence given by an effective combinatorial (reduction) algorithm on the digraph $\Gamma$.

The W(E6)$W(E_6)$‐invariant birational geometry of the moduli space of marked cubic surfaces
Mathematische Nachrichten, Volume 297, Issue 7, Page 2639-2666, July 2024.Abstract The moduli space Y=Y(E6)$Y = Y(E_6)$ of marked cubic surfaces is one of the most classical moduli spaces in algebraic geometry, dating back to the nineteenth‐century work of Cayley and Salmon. Modern interest in Y$Y$ was restored in the 1980s by Naruki's explicit construction of a W(E6)$W(E_6)$‐equivariant smooth projective compactification Y¯$

K3 surfaces with a symplectic automorphism of order 4
Mathematische Nachrichten, Volume 297, Issue 6, Page 2302-2332, June 2024.Abstract Given X$X$, a K3 surface admitting a symplectic automorphism τ$\tau$ of order 4, we describe the isometry τ∗$\tau ^*$ on H2(X,Z)$H^2(X,\mathbb {Z})$. Having called Z∼$\tilde{Z}$ and Y∼$\tilde{Y}$, respectively, the minimal resolutions of the quotient surfaces Z=X/τ2$Z=X/\tau ^2$ and Y=X/τ$Y=X/\tau$, we also describe the maps induced in ...

Journal of the London Mathematical Society, Volume 109, Issue 6, June 2024.Abstract We construct a family of solvable lattice models whose partition functions include p$p$‐adic Whittaker functions for general linear groups from two very different sources: from Iwahori‐fixed vectors and from metaplectic covers. Interpolating between them by Drinfeld twisting, we uncover unexpected relationships between Iwahori and metaplectic ...

The generalized Harer conjecture for the homology triviality
Bulletin of the London Mathematical Society, Volume 56, Issue 5, Page 1879-1895, May 2024.Abstract The classical Harer conjecture states the stable homology triviality of the canonical embedding ϕ:B2g+2↪Γg$\phi: B_{2g+2} \hookrightarrow \Gamma _{g}$, which was proved by Song and Tillmann. The main part of the proof is to show that Bϕ+:BB∞+→BΓ∞+$\operatorname{B}\phi ^{+}: \operatorname{B}B_{\infty }^{+} \rightarrow \operatorname{B}\Gamma _ ...

Singular CR structures of constant Webster curvature and applications
Mathematische Nachrichten, Volume 297, Issue 3, Page 943-961, March 2024.Abstract We consider the sphere S2n+1$\mathbb {S}^{2n+1}$ equipped with its standard contact form. In this paper, we construct explicit contact forms on S2n+1∖S2k+1$\mathbb {S}^{2n+1}\setminus \mathbb {S}^{2k+1}$, which are conformal to the standard one and whose related Webster metrics have constant Webster curvature; in particular, it is positive if ...

Multigraded algebras and multigraded linear series
Journal of the London Mathematical Society, Volume 109, Issue 3, March 2024.Abstract This paper is devoted to the study of multigraded algebras and multigraded linear series. For an Ns$\mathbb {N}^s$‐graded algebra A$A$, we define and study its volume function FA:N+s→R$F_A:\mathbb {N}_+^s\rightarrow \mathbb {R}$, which computes the asymptotics of the Hilbert function of A$A$. We relate the volume function FA$F_A$ to the volume

Logarithmic bounds on Fujita's conjecture
Proceedings of the London Mathematical Society, Volume 128, Issue 3, March 2024.Abstract Let X$X$ be a smooth complex projective variety of dimension n$n$. We prove bounds on Fujita's basepoint freeness conjecture that grow as nloglog(n)$n\operatorname{log}\operatorname{log}(n)$, where log$\operatorname{log}$ is the logarithm with natural base.
