In this paper, we consider the integral of a stochastic process with respect of a sequence of square integrable semimartingales. By this integrals, we construct a reproducing kernel Hilbert space and study the correspondence between this space with the concepts of arbitrage and viability in mathematical finance.
On 2-inner product spaces and reproducing property
Saeed Hashemi Sababe 강원경기수학회 2020 한국수학논문집 Vol.28 No.4
This paper is devoted to study the reproducing property on 2-inner product Hilbert spaces. We focus on a new structure to produce reproducing kernel Hilbert and Banach spaces. According to multi variable computing, this structures play the key role in probability, mathematical finance and machine learning.
A NEW CLASS OF RIEMANNIAN METRICS ON TANGENT BUNDLE OF A RIEMANNIAN MANIFOLD
Baghban, Amir,Sababe, Saeed Hashemi Korean Mathematical Society 2020 대한수학회논문집 Vol.35 No.4
The class of isotropic almost complex structures, J<sub>𝛿,𝜎</sub>, define a class of Riemannian metrics, g<sub>𝛿,𝜎</sub>, on the tangent bundle of a Riemannian manifold which are a generalization of the Sasaki metric. This paper characterizes the metrics g<sub>𝛿,0</sub> using the geometry of tangent bundle. As a by-product, some integrability results will be reported for J<sub>𝛿,𝜎</sub>.
A new class of Riemannian metrics on tangent bundle of a Riemannian manifold
Amir Baghban,Saeed Hashemi Sababe 대한수학회 2020 대한수학회논문집 Vol.35 No.4
The class of isotropic almost complex structures, $J_{\delta , \sigma}$, define a class of Riemannian metrics, $g_{\delta , \sigma}$, on the tangent bundle of a Riemannian manifold which are a generalization of the Sasaki metric. This paper characterizes the metrics $g_{\delta , 0}$ using the geometry of tangent bundle. As a by-product, some integrability results will be reported for $J_{\delta , \sigma}$.

Shabani, Mohammad Mehdi,Yazdi, Maryam,Sababe, Saeed Hashemi Department of Mathematics 2021 Kyungpook mathematical journal Vol.61 No.2
In this paper, we investigate harmonic univalent functions convex in the direction 𝜃, for 𝜃 ∈ [0, 𝜋). We find bounds for |f<sub>z</sub>(z)|, ${\mid}f_{\bar{z}}(z){\mid}$ and |f(z)|, as well as coefficient bounds on the series expansion of functions convex in a given direction.
SOME DISTORTION THEOREMS FOR NEW SUBCLASS OF HARMONIC UNIVALENT FUNCTIONS
( Mohammad Mehdi Shabani ),( Maryam Yazdi ),( Saeed Hashemi Sababe ) 호남수학회 2020 호남수학학술지 Vol.42 No.4
We introduced and studied a new class of harmonic univalent functions on unit disc U. Also we provided coefficient conditions, extreme points and convolution conditions for that class of harmonic univalent functions.
An Iterative Method for Equilibrium and Constrained Convex Minimization Problems
Yazdi, Maryam,Shabani, Mohammad Mehdi,Sababe, Saeed Hashemi Department of Mathematics 2022 Kyungpook mathematical journal Vol.62 No.1
We are concerned with finding a common solution to an equilibrium problem associated with a bifunction, and a constrained convex minimization problem. We propose an iterative fixed point algorithm and prove that the algorithm generates a sequence strongly convergent to a common solution. The common solution is identified as the unique solution of a certain variational inequality.
Mohammad Mehdi Shabani,Saeed Hashemi Sababe 강원경기수학회 2022 한국수학논문집 Vol.30 No.1
In this article, we represent and examine a new subclass of holomorphic and bi-univalent functions defined in the open unit disk $\mathfrak{U}$, which is associated with the Dziok-Srivastava operator. Additionally, we get upper bound estimates on the Taylor-Maclaurin coefficients $|a_{2}|$ and $|a_{3}|$ of functions in the new class and improve some recent studies.

Mohammad Mehdi Shabani,Saeed Hashemi Sababe 강원경기수학회 2020 한국수학논문집 Vol.28 No.1
In this paper, we introduce two subclasses of analytic and Spiral-like functions and investigate convolution properties, the necessary and sufficient condition, coefficient estimates and inclusion properties for these classes.

The effects of variations in annual, seasonal, and extreme precipitation in the Han River Basin (HRB) were explored using innovative trend analysis, Spearmen’s rho test, and Mann-Kendall test. Extreme-value precipitation was analyzed using various precipitation categories (light, low, moderate, high, and extreme). Stations in the north and northeast parts of the basin were more sensitive to precipitation inconsistencies. Hydrologically extreme events such as flood and drought were associated with extreme (> 90th percentile) and light (< 10th percentile) precipitation categories. Significant variability was detected in summer precipitation, whereas annual and extreme precipitation trends were more sensitive in the northeastern parts of the basin, signifying possible flooding aggregation. However, a decrease in flooding in the southern HRB indicated a shift in the precipitation regime from south to north. Overall results suggest that the eastern and northwestern regions were more likely to experience extreme floods during the summer and severe droughts during the fall and winter. An increase in precipitation was observed over time from the south to the north. A warming and wetting trend was observed in the north, while a warming-drying trend was evident in the south. Mitigating hydro-meteorological disasters such as flood and drought in the HRB will require more research attention to these trends.
