Loan To Value (LTV):

LTV is the ratio between the maximum allowed borrow value and the collateral value.
Concretely, say that a user deposit 100 USD worth of SOL, according to the currently LTV of 85% for Solana the users are able to borrow up to 85 USD worth of assets

Liquidation Threshold:

Liquidation threshold is the ratio between borrow amount and the collateral value at which the users are subject to liquidation.
Concretely, say that a user deposit 100 USD worth of SOL and borrow 85 USD worth of assets, according to the currently liquidation threshold of 90%, the user is subject to liquidation if the value of the assets that they borrow has increased 90 USD.

Liquidation Bonus

Liquidation bonus is the extra amount of collateral that the liquidator will get for taking the risk of liquidating the users.
As an example, if the user has put in 100 USD worth of SOL and borrow 85 USD. If the value of the borrowed asset has reached 90 USD. The liquidator can comes in and pay 50 USD worth of SOL and it will be able to get back 50 * (1 + 2%) = 51 USD worth of SOL.
