Boundedness of klt complements on Fano fibrations over surfaces
Full text linkLet be an -lc pair of dimension with a closed point
. Birkar conjectured that there is an effective Cartier divisor
passing through such that is lc near , where is a
positive real number depending only on . We prove that Birkar's
conjecture is equivalent to Shokurov's conjecture on boundedness of klt
complements on Fano fibrations and we confirm Birkar's conjecture in dimension
2. As a corollary, we prove the boundedness of klt complements on Fano
fibrations over surfaces.Comment: Version 2, showed that Shokurov's conjecture implies Birkar's
conjecture, so they are equivalent (see Theorem 1.6). Version 3, added
Example 1.10 to indicate that the order O(\epsilon^2) in Theorem 1.7 is

The literary and translatory perception of A. N. Ostrovsky’s play "Without a dowry" in China
No full textThe article is devoted to the reception of one of the most famous plays of A. N. Ostrovsky in China – “Without a Dowry”. The play belongs to the late period of the playwright's work and is characterised by a complex genre. In Russian literary studies it is considered as a socio-psychological drama with a bright lyrical beginning. The aim of the article is to give an idea of the translation, literary and literary perception of the play in China. The author of four versions of the play's translation into Chinese, Chen Bingyi, analyses the peculiarities of the play's translation. It reveals the main aspects of literary research on the play in China and examines the particular understanding of “Without a Dowry” by the playwright and translator Chen Baichen. By comparing the plots of A.N. Ostrovsky's drama and Chen Baichen’s drama “Love on a Steep Cliff”, the article highlights the influence of the character Katerina from the famous play “The Storm” on the interpretation of the female protagonist and the genre characteristics of “Without a Dowry”. The analysis demonstrates that Chinese translators, literary critics, and playwrights collectively perceive this psychological drama by Ostrovsky as a social drama within the historical and cultural context of 1940s China
Singularities on vertical -log canonical Fano fibrations
No full textGiven a Fano type log Calabi-Yau fibration with being -lc, the first author in \cite{Bi23} proved that the generalised pair given by the canonical bundle formula is generalised -lc where depends only on and , which confirmed a conjecture of Shokurov. In this paper, we prove the above result under a weaker assumption. Instead of requiring to be -lc, we assume that is -lc vertically over , that is, the log discrepancy of with respect to is for any prime divisor over whose center on is vertical over .11 pages, comments welcom
The impact of audit quality on the pricing of fair value estimates in the banking industry
Full text linkIn recent years, the Public Company Accounting Oversight Board’s (PCAOB) inspections have frequently reported audit deficiencies related to fair value measurements. Motivated by PCAOB’s concern, this paper examines investors’ perceptions on audit quality of fair value measurements. Using a sample of U.S. public banks from 2008 through 2013, I document a significant positive (negative) association between stock prices (bid-ask spreads) and audit quality of fair value measurements. This finding indicates that audit quality adds incremental value to investors as it mitigates reliability concerns relating to fair value estimates. Furthermore, using the fair value hierarchy mandated by Statement of Financial Accounting Standards (FAS) 157, I find the audit quality effect is stronger for Level 3 fair value estimates; suggesting high audit quality mitigates the reliability concerns relating to the substantial estimation uncertainties and management bias inherent in the more opaque Level 3 financial assets. Additional cross-sectional evidence shows that the effect of audit quality on the pricing of fair value estimates is greater for smaller banks and banks with a declining regulatory capital
Explicit bound for singularities on toric fibrations
Full text linkIt was conjectured by McKernan and Shokurov that for any Fano contraction
of relative dimension with being -lc, there is a

and the multiplicity of the fiber of over a codimension one point of is
bounded above by . Recently, this conjecture was confirmed by Birkar.
In this paper, we give an explicit value for in terms of
in the toric case, which belongs to as .

and Borisov.Comment: 15 pages, comments welcom
Optimal bound for singularities on Fano type fibrations of relative dimension one
Full text linkLet be a Fano type fibration with and let be an -lc pair with K_X+B\sim_{\RR} 0/Z. The canonical bundle formula gives where is the discriminant divisor and is the moduli divisor which is determined up to \RR-linear equivalence. Shokurov conjectured that one can choose such that is -lc where only depends on . Very recently, this conjecture was proved by Birkar \cite{Bir23}. For and , Han, Jiang and Luo \cite{HJL22} gave the optimal value of . In this paper, we give the optimal value of for and arbitrary .Improve the bound in the main result (Theorem 1.4) to be optima
