Advance Mathematics , Probability & Statistics

Hi, Thank you for visiting my profile. I am Dr. Sudhir Singh (Ph.D., Mathematics, National Institute of Technology, Trichy, India). I am an expert in advanced/college-level mathematics, including differential equations, linear algebra, abstract algebra, discrete mathematics, probability & statistics, operation research, graph theory, discrete mathematics, mathematical finance, calculus, real/complex/, mathematical modelling, physics and graduate courses in mathematics and statistics. I have completed my [login to view URL]. degree in Mathematics, Physics and Statistics (2011-2014), and [login to view URL]. in mathematics (2014-2016). I completed my Ph.D., in mathematics (2017-2023) from National Institute of Technology, Trichy, India. I use software such as MATLAB/PYTHON/MATHEMATICA/MAPLE for mathematical modelling/simulations. Previously, I have worked for some online companies, including Tutorbro ([login to view URL]) and Translator ([login to view URL]). Mainly, I worked as an assignment solver/tutor. Also, I am an Advanced Mathematics Expert at CHEGG ([login to view URL]). In my college days ([login to view URL].-[login to view URL].)(2011-2016), I was a home tutor and taught mathematics, physics and chemistry daily four to six hours to 6th-12th class students. Also, I taught/tutored in institutions for [login to view URL]./[login to view URL] students. Also, I taught for competitive national level exams, including NTSE, IIT-JEE, GATE and JAM. I am involved in teaching/tutoring mathematics/statistics/physics for 11 years. I enjoy teaching a lot. My publications includes 1) Benjamin-Ono equation: Rogue waves, generalized breathers, soliton bending, fission, and fusion: Eur. Phys. J. Plus (2020) 135: 823. 2) Dynamics of higher-order bright and dark rogue waves in a new (2+1)-dimensional integrable Boussinesq model, Phys. Scr. [login to view URL]. 3) Computing solitary wave solutions of coupled nonlinear Hirota and Helmholtz equations: Physica A 560 (2020) 125114 4) Dynamics of optical solitons and conservation laws of a new (2+1)-dimensional integrable nonlinear evolution equation in deep water oceanic waves: Modern Physics Letters B Vol. 34, No. 5 ([login to view URL] , DOI: 10.1142/S0217984920500682. 5) Dust ion acoustic multi-shock wave excitations in the weakly relativistic plasmas with nonthermal nonextensive electrons and positrons: AIP Advances 10, 065234 (2020); doi: 10.1063/5.0011086 6) Computing exact solutions and conservation laws of conformable time-fractional Gardner and Benjamin-Ono equations-Accepted for publication in Pramana-Journal of Physics, Springer I am VERY MUCH interested in mathematics/statistics, and I enjoy very much doing it. I am very hard working and very committed to work. I deliver the finished project in minimum time duration. My availability is 24/7. I would be pleased to help/work anything related to mathematics/statistics/physics. Best wishes Sudhir Singh Research Scholar Department of Mathematics National Institute of Technology, Trichy, India

HIGHLY RECOMMENDED! Would give him more than 5 stars! Sudhir is a very motivated and result oriented person. He treats your project like his own and ensures that he gives his very best and achieves more than what you would expect. I was failing in my math class and had 30% in the class before I hired Sudhir. With limited time and a very hard syllabus, Sudhir's expert tutoring helped me pass the class and my marks doubled. Sudhir went above and beyond teaching me for hours sometimes late in the night. He was very professional and provided me with great study notes and material. And all of this was provided at a very reasonable price which included extra hours in which Sudhir never even brought up money because he was so focused on my goals. BEST HIRE FOR ANY PROJECT OR TUTORING!

https://arxiv.org/pdf/2004.09463.pdf Rogue waves and breathers are one of the very interesting localized nonlinear structures. Although, the appearance of rogue waves are not limited to ocean but in finance, plasma, superfluid, Bose-Einstein condensate and well known optical rogue waves. The mathematical justification of these nonlinear structures are always an interesting task.
