A Predictor-Corrector Methods for Mixed Inverse Variational Inequalities [PDF]
, 2009 In this paper, a class of mixed inverse variational inequalities is introduced and studied. We prove the existence of the solution of the auxiliary problem for mixed inverse variational inequalities, suggest a predictor-corrector method for solving the ...

A New Variational Inequality with its Application [PDF]
, 2009 In this paper, we suggest the iterative algorithm for a variational inequality by using the auxiliary principle technique, which is closely related to the optimal boundary control of time-varying population system with age-dependence and spatial ...

Invariant variation problems [PDF]
Transport Theory and Statistical Physics, 1971 The problems in variation here concerned are such as to admit a continuous group (in Lie's sense); the conclusions that emerge from the corresponding differential equations find their most general expression in the theorems formulated in Section 1 and proved in following sections.

Coisotropic variational problems [PDF]
Journal of Geometry and Physics, 2004 In this article we study constrained variational problems in one independent variable defined on the space of integral curves of a Frenet system in a homogeneous space G/H. We prove that if the Lagrangian is G-invariant and coisotropic then the extremal curves can be found by quadratures. Our proof is constructive and relies on the reduction theory for

Variations on the Two-Child Problem
The Mathematical Intelligencer, 2023 Abstract Mr. Smith has two children. Given that at least one of them is a boy, how likely is it that Mr. Smith has two boys? It’s a very standard puzzle in elementary books on probability theory. Whoever asks you this question hopes that you will answer “1/2”, in which case they can say triumphantly “Oh no, the answer is 1/3 ”.

Variational approach to the construction of discrete mathematical model of the pendulum motion with vibrating suspension with friction [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамика, 2022 The main purpose of this work is, first, a construction of the indirect Hamilton’s variational principle for the problem of motion of a pendulum with a vibration suspension with friction, oscillating along a straight line making a small angle with ...

A one-dimensional variational problem with continuous Lagrangian and singular minimizer [PDF]
, 2010 We construct a continuous Lagrangian, strictly convex and superlinear in the third variable, such that the associated variational problem has a Lipschitz minimizer which is non-differentiable on a dense set.

On a variation of the Oberwolfach problem
Discrete Mathematics, 1979 AbstractWe consider the following “spouse-avoiding” variant of the Oberwolfach problem (briefly NOP): “At a gathering there are n couples. Is it possible to arrange a seating for the 2n people present at s round tables T1,T2,…,Ts (where Ti can accomodate ki ⩾ 3 people and Σki=2n) for m different meals so that each person has every other person except ...
