This three-part treatment of partial differential equations focuses on elliptic and evolution equations. Largely self-contained, it concludes with a series of independent topics directly related to the methods and results of the preceding sections that helps introduce readers to advanced topics for further study. Geared toward graduate and postgraduate students of mathematics, this volume also constitutes a valuable reference for mathematicians and mathematical theorists.Starting with the theory of elliptic equations and the solution of the Dirichlet problem, the text develops the theory of weak derivatives, proves various inequalities and imbedding problems, and derives smoothness theorems. Part Two concerns evolution equations in Banach space and develops the theory of semigroups. It solves the initial-boundary value problem for parabolic equations and covers backward uniqueness, asymptotic behavior, and lower bounds at infinity. The final section includes independent topics directly related to the methods and results of the previous material, including the analyticity of solutions of elliptic and parabolic equations, asymptotic behavior of solutions of elliptic equations near infinity, and problems in the theory of control in Banach space.

shimmer
Color: Rose Gold
I recently tried the UCANBE Body Shimmer Oil, and I have to say, I'm really impressed! The oil has a beautiful, subtle shimmer that adds a touch of glow without being too overpowering. It feels luxurious on the skin, absorbing quickly and leaving it soft and smooth. I love how it gives my skin a healthy, radiant look, especially when I wear it on my legs and arms. The scent is light and refreshing, not too strong, which is a plus for me. Overall, it's perfect for a little extra sparkle on special occasions or just when I want to feel a bit extra on a regular day! Definitely recommend it if you're looking for a quality shimmer oil that doesn't feel greasy.

Bad Batch
Color: Gold
It was so thick & stinky. Had to toss it and take a shower right away. Couldn’t get it off my skin.

A Staple in Skin Care Routine
Style: Milky Toner
This toner has become a staple in my skincare routine. I have sensitive skin and a lot of products tend to cause irritation or redness, but this one has been incredibly gentle from the start. My skin always feels soft, calm, and hydrated after using it.
The texture is lightweight with an almost soapy feel at first, but it absorbs quickly and never leaves my skin feeling greasy or heavy. It layers well with the rest of my skincare and works great both morning and night. I also appreciate that it gives results similar to more expensive brands without the high price tag. Definitely one of the better affordable skincare products I’ve tried.

My Favorite Product in the Milky Line
Style: Milky Toner, Style: Milky Toner
This toner has easily become my favorite product from Thayers brand and all other brands. I’m very picky about my skincare routine, especially when it comes to products I use daily, and this one has completely earned a permanent spot in my routine.
It feels incredibly gentle, hydrating, and soothing on the skin without feeling sticky or heavy. I love the ingredients, especially the snow mushroom and hyaluronic acid, because my skin always feels soft, balanced, and refreshed after using it. I’ve also noticed my pores looking smoother and overall healthier since incorporating this toner consistently.
The formula works beautifully with the rest of the Milky line, and my skin genuinely looks and feels better when I use it regularly. I’ll absolutely continue repurchasing this product.
