A Riemann-Hilbert correspondence for cohomology theories of closed 1-forms
Yota Shamoto
Motivated by the work of Kontsevich-Soibelman on the comparison of isomorphisms conjecture for closed algebraic -forms, we establish a Riemann-Hilbert correspondence of Deligne-…
A Subgeometric Convergence Formula for Total-variation Error of the Level-increment Truncation Approximation of M/G/1-type Markov Chains
Katsuhisa Ouchi, Hiroyuki Masuyama
This paper considers the level-increment (LI) truncation approximation of M/G/1-type Markov chains. The LI truncation approximation is usually used to implement Ramaswami's recursi…
Analysis of the Impact of High-Frequency Trading on Artificial Market Liquidity
Isao Yagi, Yuji Masuda, Takanobu Mizuta
Many empirical studies have discussed market liquidity, which is regarded as a measure of a booming financial market. Further, various indicators for objectively evaluating market…
Stokes filtered sheaves and differential-difference modules
Yota Shamoto
We introduce the notion of Stokes filtered quasi-local systems. It is proved that the category of Stokes filtered quasi-local systems is abelian. We also give a geometric way to co…
Stability conditions on morphisms in a category
Kotaro Kawatani
Let be the homotopy category of a stable infinity category . Then the homotopy category of morphisms in the sta…
High-voltage Pulse Generation Based on Relaxed Self-Excited Oscillation Using Electrostatic Induction in External Capacitors
Taku Saiki
Simple method of producing high voltage pulses with short rising times based on electrostatic induction in external capacitor used for pulse power applications is proposed. The cir…
On the Refracted-Reflected Spectrally Negative Lévy Processes
José-Luis Pérez, Kazutoshi Yamazaki
We study a combination of the refracted and reflected Lévy processes. Given a spectrally negative Lévy process and two boundaries, it is reflected at the lower boundary while, when…
