Abstract: We consider the indefinite linear-quadratic optimal control problem for stochastic systems with random coefficients, where the corresponding cost parameters need not be definite matrices.

Math. It’s that five-letter word that still manages to haunt the dreams of both high school sophomores and overworked college students alike. Derivatives, matrices, word problems that somehow involve ...

Abstract: Mean field game theory has been developed largely following two routes. One of them, called the direct approach, starts by solving a large-scale game and next derives a set of limiting ...

This paper assesses empirically the sign of the uncertainty-investment relation in Brazil within a quadratic adjustment cost model. It is shown that these variables are negatively related in the ...

The Simulated Bifurcation (SB) algorithm is a fast and highly parallelizable state-of-the-art algorithm for quadratic combinatorial optimization inspired by quantum physics and spins dynamics. It ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

A team of international physicists has brought Bayes’ centuries-old probability rule into the quantum world. By applying the ...

If the mention of algebra conjures bad memories of math classes, a Python library called SymPy could change your mind about ...

The CBSE Class 10 Board Exams 2026 will begin on 17 February 2026 with Mathematics, followed by English (21 Feb), Science (25 ...

Factorising is the reverse process of expanding brackets. A factorised answer will always contain a set of brackets. Factorise \(6x + 9\). To factorise this expression, look for the HCF of \(6x\)and 9 ...

Gordon Scott has been an active investor and technical analyst or 20+ years. He is a Chartered Market Technician (CMT). A line of best fit is a form of regression analysis that shows the relationship ...
